regexp: skip long-running benchmarks if -short is specified

This CL helps race.bash finish in a reasonable amount of
time. Otherwise the Match/Hard1/32M benchmark takes over 1200 seconds
to finish on arm64, triggering a timeout.  With this change the regexp
benchmarks as a whole take only about a minute.
