[PATCH] check-ignore: fix mix of directories and other file types

[René Scharfe]

In check_ignore(), the first pathspec item determines the dtype for any
subsequent ones.  That means that a pathspec matching a regular file can
prevent following pathspecs from matching directories, which makes no
sense.  Fix that by determining the dtype for each pathspec separately,
by passing the value DT_UNKNOWN to last_exclude_matching() each time.
