graphviz: remove obsolete and problematic patch

Remove 0001-Set-use_tcl-to-be-empty-string-if-tcl-is-disabled.patch.

This patch is obsolete and not needed because the current graphviz
configure.ac has correct logic of checking use_tcl. This use_tcl
variable needs to be set when '--disable-tcl' is set, otherwise,
things will behave as if no option is supplied and the configure
process will check tcl automatically.

This patch is problematic because its logic against the current version
is wrong. The recipe has already explicitly set '--disable-tcl', so
the configure process should not do automatic checking for tcl at do_configure.

This patch fixes do_configure error when host has tcl8.6-dev installed. The
error is like below:

  QA Issue: This autoconf log indicates errors, it looked at host include and/or
  library paths while determining system capabilities.
  Rerun configure task after fixing this. [configure-unsafe]
