File reproducible.patch of Package python-qt4

have constant link order
to make builds reproducible.
See https://reproducible-builds.org/ for why this is good.

Without this patch g++ would order functions in .so files
depending on random order of files in the build system's filesystem.

Note that we also need to sort .h files because those are used
to create .cpp files with moc.
