brew: error out if bad xcode-select path given

Since a bad xcode-select path can cause many brew commands to freeze,
it's worth warning users and bailing out as early as possible.

The doctor check wasn't good enough, since the doctor could freeze
before the warning about this was ever printed.

Your xcode-select path is currently set to '/'.
This causes the `xcrun` tool to hang, and can render Homebrew unusable.
If you are using Xcode, you should:
sudo xcode-select -switch /Applications/Xcode.app
Otherwise, you should:
sudo rm -rf /usr/share/xcode-select
