[PATCH] am: pass exclude down to apply

[maximilian attems <max@stro.at>]

This allows to pass patches around from repositories,
where the other repository doesn't feature certain files.

In the special case this works for dash git sync to klibc dash:
 git am --directory="usr/dash" --exclude="usr/dash/configure.ac" \
        --exclude="usr/dash/ChangeLog" --exclude="usr/dash/dash.1" \
	.. -i -s -k ../dash/000X-foo.patch

This is a resent, haven't a test for this usecase,
but it is useful and simple enough, so reposted.
