[Intel-gfx] [PATCH i-g-t 5/9] lib/kunit: Omit suite name prefix if the same as subtest name

[Janusz Krzysztofik]

Kunit test modules usually contain one test suite, named after the module
name with the trailing "_test" or "_kunit" suffix omitted.  Since we
follow the same convention when we derive subtest names from module names,
there is a great chance that those two names match.  Take this into
account when composing names for IGT dynamic sub-subtest names and drop
the leading test suite name component when it is the same as subtest name.
