Subject: [PATCH] tests: add basic infrastructure for regression tests

The patch adds tests/ directory with simple regression tests infrastructure.

Also, it adds the "ts-mount-paths" test that testing if all defined paths
(fstab, mtab, locks) are still same.

Signed-off-by: Karel Zak <kzak@redhat.com>
