tools: Touch Makefile.in after applying patches

If a patch changes configure.ac, but no Makefile.am, then the generated
build system patch will end up making configure and aclocal.m4 newer
than Makefile.in, and thus a downstream build wants to call automake to
update it. Avoid this by forcing Makefile.in to be as new as the patched
files.

Closes #9878
