util/gitconfig: Add timeout test

Add a `util/gitconfig/test` subdirectory which will contain tests to run
as executable files, add a helper script.

Add a timeout test that verifies that gitconfig completes in under two
seconds (typical run time is ~30 ms). Add gitconfig tests to the
`testing` Makefile under the `test-tools` target.
