If multiple kegs, default to formula keg

Browse Source 
If it exists, ARGV.kegs will return the Formula.prefix keg for each rack examined.

So for ARGV=[wget, foo] and the following Cellar (wget/1.11, wget/1.12, foo/1.0) you'll get [wget/1.12, foo/1.0] from ARGV.kegs provided 1.12 is the formula version of wget.
