git: Properly wrap Git commands that are implemented in Perl. (#30001)

Some Git commands are implemented as Perl scripts. Some of these scripts use Perl modules from CPAN. Without wrapping these programs to set `GITPERLLIB`, these programs would not be fully functional because some Perl libraries are found to be missing at runtime. Fixes #29996
