selftest: make filter-subunit much more efficient for large knownfail lists

By compiling the knownfail lists ahead of time we change a 20min test
into a 90sec test.

This could be improved further by combining this into a single regular expression,
but this is enough for now.  The 'reason' is thankfully not used.
