[PATCH 13/13] t: add test harness for external credential helpers

We already have tests for the internal helpers, but it's nice to give authors of external tools an easy way to sanity-check their helpers.

If you have written the "git-credential-foo" helper, you can do so with:

  GIT_TEST_CREDENTIAL_HELPER=foo \
  make t0303-credential-external.sh

This assumes that your helper is capable of both storing and retrieving credentials (some helpers may be read-only, and they will fail these tests).

If your helper supports time-based expiration with a configurable timeout, you can test that feature like this:

  GIT_TEST_CREDENTIAL_HELPER_TIMEOUT="foo --timeout=1" \
  make t0303-credential-external.sh

I haven't tried porting or testing any of the older helpers to the new
interface. So this script has only been lightly tested with:

  GIT_TEST_CREDENTIAL_HELPER=cache
