Moving duplicated code into the new function match_stat_with_submodule().
Replacing the implicit activation of detailed checks for the dirtiness of
submodules when DIFF_FORMAT_PATCH was selected with explicitly setting
the recently added DIFF_OPT_DIRTY_SUBMODULES option in diff_setup_done().

All tests run fine with this patch. All other callsites where the option
DIFF_FORMAT_PATCH is set look like they don't deal with the work tree
or they call diff_setup_done() shortly after.
I am pretty sure about builtin/log.c, as this can't use the work tree
but only already commited stuff, no?
But then there is edit_patch() in buitin/add.c, I am not sure it makes
sense to set DIRTY_SUBMODULES there too. Opinions?
