Johannes Berg a5d7da3fd3 hwsim tests: Prefill database in VM tests
In some cases, e.g., with the VM tests if the VM crashes, it
can be useful to know which tests should have run but didn't
(or didn't finish). In order to catch these more easily, add
an option to prefill the database with all tests at the very
beginning of the testing (in a new NOTRUN state) and use the
option in the VM tests.
