We are compiling regex more than 300000 times, and it's a main
bottleneck for slow sepolicy_tests. Actually we don't need to compile
regex that much; most of cases can be handled by simple string
comparison. This change introduces heuristics for optimization.
Bug: 301874100
Test: verified that return values of MatchPathPrefix are not changed.
Test: run cProfile, before and after.
