Hi Cyril,

thanks for previous review. I modified the test more thus sending v2.

Changes v1-v2:
* Check two version of module (using '_' and '-' also on built-in
  modules) => more coverage.
* Fix test when $MODULES_DIR exists, but does not contain modules
(in v1 it TBROK: Test didn't report any results), now at least check non-existing module:

Kind regards,
Petr

tst_check_driver 2 TINFO: check non-existing module detection
tst_check_driver 2 TPASS: tst_check_drivers not-existing-kernel-module failed as expected
tst_check_driver 3 TINFO: check built-in module detection
