[PATCHv5 01/17] t/test-lib.sh: Export also GIT_BUILD_DIR in test_external

[Jakub Narebski <jnareb@gmail.com>]

This way we can use it in test scripts written in other languages
(e.g. in Perl), and not rely on "$TEST_DIRECTORY/.."

This is not strictly required, but if we modified t/gitweb-lib.sh to
use GIT_BUILD_DIR, we would want to do the same in the test scripts
for caching interface etc. included in this series.

This patch was not present in previous version of this series, and it
has no equivalent in original patch by J.H.
