mime: short circuit short globs2 glob exclusion

Browse Source 
Applied on top of previous changes, this will only exclude the
hypothetical *. which is unlikely to be in globs2 files out there. But
because we're checking for the length anyway, we might as well bump the
minimum length to 3 (includes * and .) to short circuit exclusion of too
short entries.
