[PATCH] add a test for recently introduced loop-dev-based bug

[Soren Hansen]

This also checks for the current behavior when trying to partition
a device that may not be partitioned, like loop devices.
* tests/Makefile.am (TESTS): Add tests/t8000-loop.sh.
* tests/t8000-loop.sh: New file.  Test for the above fix.
