Revert "benchmark/*.yml: convert from benchmark/bm_*.rb"

Browse source 
This reverts r63900.

Having single-execution benchmark as a normal Ruby script is preferred
by ko1. I'm not a big fan of having inconsistent benchmark formats, but
I can understand some benefits of it.

common.mk: remove obsolsted benchmark-each PHONY declaration, support
running Ruby scripts added by this commit.
