test: skip all subtests if external dependencies are missing during init

Some tests (e.g. crypto) do a common initialization required for all
subtests.  The patch adds a check for missing external dependencies
during this initialization.  If any prerequisites are missing, all
subtests are skipped.

The check is run on the first call of test_reset_state_ function, so
no changes for the tests are needed.
