doctor: don't let gitconfig break dirty-tree check

Browse Source 
`brew doctor` always complains about uncommitted modifications to
Homebrew when you have status.branch=true in your git config, because
the implicit --branch makes `git status -s` always print branch/tracking
info. The --porcelain mode is similar to -s/--short, but ignores most of
the user's config and should remain stable.

The --untracked-files option ensures we'll see untracked files even for
users with status.showUntrackedFiles=no, which is not suppressed by
--porcelain for some reason.

Closes Homebrew/homebrew#25230.

You have uncommitted modifications to Homebrew
If this a surprise to you, then you should stash these modifications.
