Title: Fix check for installed packages which always errors when upgrade is not required.

Appears to fix chef crash when `brew outdated | grep blah` exits with status 1 (which it would do any time a package is not outdated.)

Testing this is a little tricky as I'm not sure how to get homebrew to downgrade a package in a way such that it then realizes it is outdated.
