test_utils.c: Skip test adsi_loaded_test if module not loaded.

Module res_adsi.so is deprecated, therefore it does not load by default.
Module not loaded causes it to yield a FAIL when tested by tests/test_utils.c.
This fix checks if the corresponding module is loaded at the start of the test,
and if not, it passes the test and exits with a message.

This fix is applied to all versions where the module is marked deprecated.
