[PATCH] Define $PERL_PATH in test-lib.sh

["Philippe Bruhat (BooK)" <book@cpan.org>]

The main Makefile defines PERL_PATH as the perl to use in the shebang
line of git*.perl commands. This ensures this will be the perl used
to run the tests (in case another perl appears in $PATH before the one
defined in $PERL_PATH)
