Using the regular gitcommit highlighter would not make sense, as it is intended for the message templates seen when making a commit. Whereas format-patch .patch files have the headers as email headers.

You can load the mail header highlighting on top of diff highlighting like this (which only triggers for patches that look like emails):

  au FileType diff
    \ if getline(1) =~ '^From ' |
    \   unlet b:current_syntax |
    \   runtime! syntax/mail.vim |
    \ endif

But maybe there is something else that you wanted to highlight. It's not clear to me what you want from gitcommit's highlighting. Is it the "complain about long lines" highlighting? I think that you'd have to pull out of the gitcommit.vim and execute manually (and you'd have to tweak the regex to take into account the "Subject: [PATCH] bits).
