scripts/run_tests.sh: remove checksum_benchmarks

The reason that run_tests.sh supported running checksum_benchmarks.sh is
that as a side effect, checksum_benchmarks.sh runs the 'test_checksums'
program with all combinations of CPU features.

However, commit ec60cb48d11c ("tools/run_tests.sh: test different
combinations of CPU features") made run_tests.sh handle this elsewhere.

So having run_tests.sh run checksum_benchmarks.sh is no longer useful.

Keep checksum_benchmarks.sh around for manual benchmark runs, however.
