Don't raise when expanding ORIGINAL_PATHS

File.expand_path raises ArgumentError when it is passed a path with a
nonexistent username, e.g.:

  $ PATH=~foo/bin:$PATH brew
  /usr/local/Library/Homebrew/global.rb:97:in `expand_path': user foo
  doesn't exist (ArgumentError)

However, `brew doctor` does its own expansion of PATH entries and
outputs warnings if this happens, so let's just ignore it here and
continue on our way.
