Make tests independent of global config files

This was done by setting $HOME to somewhere bogus. A better method is
to reuse $GIT_CONFIG, which was invented for ignoring the global
config file explicitely.

Technically, setting GIT_CONFIG=.git/config could be wrong, but it
passes all the tests, and we can keep the tests that way.
