classes/archiver: Create patched archive before configuring

do_configure and do_preconfigure can modify source files, which causes
race conditions if these tasks run in parallel with do_ar_patched. Add
explicit task dependencies to ensure that do_ar_patched finishes before
these tasks start. Specifically, this fixes a race condition with
gcc-source where do_ar_patched races with do_preconfigure deleting
gcc/gengtype-lex.c
