Benchmark: allow exclusion filters using !

This allows exclusions to be set in the `tests` filter for the
benchmarks using the exclamation mark. Exclusions apply *after*
inclusions ie:

tests = ['*', '!victor', '!koro']

would select all available tests then specifically exclude victor
and koro, while:

tests = ['!victor']

would just exclude victor, since nothing is marked for inclusion
no tests will be run.

tests = ['!victor','bmw27,'victor']

would exclude victor, but include bmw27 and victor but as victor was
marked for exclusion only bmw27 will be ran.
