[fuzzing] Lower probability of some potentially contradictory flags.

The following flag combinations run into a CHECK in d8:
('--assert-types', '--stress-concurrent-inlining')
('--assert-types', '--stress-concurrent-inlining-attach-code')

All flags can be passed as clusterfuzz trials on d8 fuzzers and lead
to poor fuzzing outcomes. This lowers their probability as a
mitigation until a better solution is found.
