Enrico Jörns 287e2ede38 bitbake: bitbake-diffsigs: fix handling when finding only a single sigfile
This fixes the following error when calling 'bitbake-dumpsig' or
'bitbake-diffsigs' when having only a single sigfile available:

| Traceback (most recent call last):
|   File "[..]/poky/bitbake/bin/bitbake-dumpsig", line 171, in <module>
|     files = find_siginfo_task(tinfoil, options.taskargs[0], options.taskargs[1])
|             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|   File "[..]/poky/bitbake/bin/bitbake-dumpsig", line 83, in find_siginfo_task
|     sig2 = latestsigs[1]
|            ~~~~~~~~~~^^^
| IndexError: list index out of range

Handle this by adding (and returning) the path for the second sigfile
only if one is found. This way it will work for both diffsigs and
dumpsig use case.

The calling argparse code already deals with find_siginfo_task()
returning only a single file.
For 'bitbake-dumpsig' it will just dump the single sigfile, for
'bitbake-diffsigs' it will emit a proper error message again:

| ERROR: Only one matching sigdata file found for the specified task (systemd configure)

Bitbake
=======

BitBake is a generic task execution engine that allows shell and Python tasks to be run
efficiently and in parallel while working within complex inter-task dependency constraints.
One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software
stacks using a task-oriented approach.

For information about Bitbake, see the OpenEmbedded website:
    https://www.openembedded.org/

Bitbake plain documentation can be found under the doc directory or its integrated
html version at the Yocto Project website:
    https://docs.yoctoproject.org

Bitbake requires Python version 3.8 or newer.

Contributing
------------

Please refer to our contributor guide here: https://docs.yoctoproject.org/contributor-guide/
for full details on how to submit changes.

As a quick guide, patches should be sent to bitbake-devel@lists.openembedded.org
The git command to do that would be:

    git send-email -M -1 --to bitbake-devel@lists.openembedded.org

If you're sending a patch related to the BitBake manual, make sure you copy
the Yocto Project documentation mailing list:

    git send-email -M -1 --to bitbake-devel@lists.openembedded.org --cc docs@lists.yoctoproject.org

Testing
-------

Bitbake has a testsuite located in lib/bb/tests/ whichs aim to try and prevent regressions.
You can run this with "bitbake-selftest". In particular the fetcher is well covered since
it has so many corner cases. The datastore has many tests too. Testing with the testsuite is
recommended before submitting patches, particularly to the fetcher and datastore. We also
appreciate new test cases and may require them for more obscure issues.

To run the tests "zstd" and "git" must be installed.

The assumption is made that this testsuite is run from an initialized OpenEmbedded build
environment (i.e. `source oe-init-build-env` is used). If this is not the case, run the
testsuite as follows:

    export PATH=$(pwd)/bin:$PATH
    bin/bitbake-selftest

The testsuite can alternatively be executed using pytest, e.g. obtained from PyPI (in this
case, the PATH is configured automatically):

    pytest
