tests: scrub environment of GIT_* variables
Variables from the inherited environment that are meaningful to git
can break tests in undesirable ways. For example,
GIT_PAGER=more sh t5400-send-pack.sh -v -i
hangs. So unset all environment variables in the GIT_ namespace in
test-lib, with a few exceptions:
- GIT_TRACE* are useful for tracking down bugs exhibited by a failing
test;
- GIT_DEBUG* are GIT_TRACE variables by another name, practically
speaking. They should probably be tweaked to follow the
GIT_TRACE_foo scheme and use trace_printf machinery some time.
- GIT_USE_LOOKUP from v1.5.6-rc0~134^2~1 (sha1-lookup: more memory
efficient search in sorted list of SHA-1, 2007-12-29) is about
trying an alternate implementation strategy rather than changing
semantics and it can be useful to compare performance with and
without it set.
