Tests use ghe-backup-config to setup special GHE_REMOTE_XXX paths

This should be a lot easier to maintain than trying to duplicate the
path adjustment logic in tests.

This change also makes it possible to run individual tests or the
entire suite against an emulated remote with e.g.,

GHE_TEST_REMOTE_VERSION=2.0.0 test/test-ghe-restore.sh
GHE_TEST_REMOTE_VERSION=11.10.340 make
