tools/coreutils: update to 9.6

Update to the next stable release.

Prevent the need for gperf to build
gperf based headers due to new gnulib versions
by skipping replacement of gperf files.

Without Automake, there are some
existing macro conflicts
due to the new version of gnulib,
causing build errors with some source files,
so skip those file replacements.

All patches are automatically refreshed.
