Fake $HOME to isolate tests from user 

On platforms with $HOME in the environment, some of our features use it
to store information in the user home directory.  However, tests for
these features should not touch the real user home directory.  Instead
we configure a fake $HOME that points inside the build tree for use
during testing.

See issue #9949.
