[PATCH v2] test-lib.sh: set PERL5LIB instead of GITPERLLIB

[Lea Wiemann <lewiemann@gmail.com>]

From: Lea Wiemann <lewiemann@gmail.com>

By setting PERL5LIB for the tests, we enable Perl test scripts to just
say "use Git;" without adding the GITPERLLIB paths to @INC beforehand.

Also, unset GITPERLLIB so that user-set paths in GETPERLLIB don't
cause the wrong module to be loaded.

Added since v1: Unset GITPERLLIB.
