graphics/gimp-app: patch configure.ac instead of configure

This makes importing upstream commits or merge requests easier in
addition to keeping track of our changes. Pre-generated configure
scripts are only present in release tarballs, but all modifications
after/separate from the fact only happen in configure.ac, so generate
the configure script every time.
