git: bump to 2.9.3, pass PERL_PATH=/bin/perl to make. (#775)

Passing /bin/perl (instead of $portPackageLinksDir/cmd~perl/bin/perl)
as PERL_PATH to make in makeGit solves the issue about perl not being
found when "haikuporter --test git" is run. FWIW, that path is used
to set the PERL and FULLPERL variables in $sourceDir/perl/perl.mak.
