Fixes HOMEBREW_PRFIX when brew is outside $PATH

If brew is called with an explicit path, eg. './bin/brew',
HOMEBREW_PREFIX is set to an empty string resulting in failure of all
brew commands using HOMEBREW_PREFIX. This commit forces Pathname to
compile an absolute path, setting HOMEBREW_PREFIX correctly.
