Geoff Parker bc7a89f5ec wic: make engine.py:get_partitions() resilient to parted/dmidecode stderr output
Running wic commands on Debian 10 systems fail in
scripts/lib/wic/engine.py:get_partitions() due to new stderr output captured
when trying to parse the output from /sbin/parted as a non-root user.

The parted command calls the dmidecode utility, which produces this error
as a non-root user:
    /sys/firmware/dmi/tables/smbios_entry_point: Permission denied
    /dev/mem: Permission denied

scripts/lib/wic/engine.py:get_partitions() calls misc.py:exec_cmd(),
a subprocess wrapper which returns a combined stderr and sdtdout.
These messages to stderr confuse the partition table parser in
get_partitions().

This patch has the partition table parser ignore lines before the expected
"BYT;" header string.

Running wic in Debian 9 does not have this issue.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
