I see no better key than moving the current key `&' to the `%' prefix.

This prefix is intended for regexp commands.  And `dired-flag-garbage-files'
is a regexp command: it uses `dired-flag-files-regexp' to flag files
that match `dired-garbage-files-regexp'.

We could even improve the command `dired-flag-garbage-files' to allow the
user to modify its default regexp value in the minibuffer after typing `% &'.
