igt/tools_test: Remove dmesg subtest

It's a silly test. If fails if there is an *ERROR* in the dmesg ringbuf,
so it neither is testing that errors are generated as expected, and as a
pre-check it can only see what's at the end of the dmesg and may miss
earlier faults. As a test it just randomly fails; worse than useless.
