[arch-general] package obsolete dependencies

Hello. 1. The "qiv" package has an obsolete dependency "libexif". The 2.2.3 Changelog says: "[tw] use gdk_pixbuf to autorotate with EXIF tags instead of libexif. Note: needs at least GDK 2.12" 2. The "libtorrent" will require makedepends=(cppunit) from the next release (it already requires it in the main svn repository). I'm terribly sorry, if I posted in a wrong place (tell me, if I did, and where to post such things next time, for I have some from time to time).
