case-lib: remove check for log ldc file

Checking for ldc (log dictionary) file existance as a way to
decide whether to enable or disable logging during a test case,
is no longer applicable as SOF supports multiple firmware logging
solutions that do not use an ldc file.

Remove the check as it no longer makes sense.
