brew --config: properly handle empty `which` strings
Symptom: If no python/ruby/perl is in your path, then `which x`.chomp
returns an empty string and `unless ""` is still true. So, N/A is never
displayed. Instead, ruby's Pathname.new("").realpath returns the cwd.
(I consider this realpath behavior a ruby bug) Fix: use empty?
Closes Homebrew/homebrew#10027.
