Use BASH instead of grep(1) 

Much like my previous commit, grep(1) isn't needed here at all. BASH
can handle REGEX as well as glob pattern matching in a very similar
way.

In this commit, I've made use of a `while read` loop to achieve the
same thing as before, but much more efficiently. If it turns out that
the `rbenv` command usually returns a crap ton of data (10s of
thousands of lines, at _least_), then please ignore this commit.
