Subject: [PATCH 2/2] selftests: lib: prime_numbers: update presence check

The test for prime numbers doesn't differentiate between missing
prime_numbers.ko and failure in prime_numbers.ko.

Update it to check for presence of the file itself to skip, therefore
correctly exercising the test failure case.
