Most of the test failures can be fixed by using the
(add-installed-pythonpath) procedure to ensure that the installed borg
can be found by the test suite.

But there are still 4 failures involving FUSE. They all fail as shown
below.

Is it expected for the build environment to have FUSE? They were skipped
with the old Python build system [0], so I've disabled them in
1d60f7c2b38733b031519a48771c44d20acb785d for
the time being.
