findutils: Use C locale to run ptests

Ensure consistent locale setting, since we are not
using make environemnt to run the tests like
upstream does. The test scripts are run explicitly

This fixes a problem with musl ptest runs where the
locale-driven quoting ends up using C.UTF-8 quotes
in gnulib’s quotearg() end up with curly quotes
instead of ASCII quote character which is expected
and result is reported as failure even though numbers
are matching.

Fixes:

-find: invalid group name or GID argument to -group: '4294967296'
+find: invalid group name or GID argument to -group: ‘4294967296’

FAIL: tests/find/user-group-max.sh
