chore: mark non-bench targets as not containing benchmarks

Cargo will otherwise look in cfg(test) modules for benchmarks, and
compile them for libtest, no criterion. This causes errors should we
ever want to pass command-line options to criterion (as libtest
obviously does not understand them). It also increases compile time (and
thus test runtime), since we needlessly compile all unittests.
