[PATCH 01/24] t/test-lib.sh: Export also GIT_BUILD_DIR in test_external

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 is the same as in previous version of this series.  It has
no equivalent in "Gitweb caching v7" by J.H.; it was not needed there
because that series doesn't have separate "unit" tests for individual
components of gitweb output caching.
