[PATCH 1/5] Export more test-related variables when running external tests

[Jakub Narebski <jnareb@gmail.com>]

Add exporting TEST_DIRECTORY and TRASH_DIRECTORY to test_external, for
external tests to be able to find test script (and git sources), and
to find trash directory (usually with test repository in it).

Add also exporting GIT_TEST_LONG, so that external test can skip
time-intensive tests unless test is invoked with `--long' option.

Currently there is no test that requires those variables; git test
suite uses test_external* only in t9700-perl-git.sh.  It would be
needed for tests of caching for gitweb.

Nevertheless I think it is a good change to have...
