Orphaning linkage

Hi, I decided to orphan this package, because upstream is almost dead (changes are done very slowly), which results into more work that needs to be done by the downstream maintainer (like keep porting it to build with a new rb_libtorrent build). If someone wants to take it feel free to do so, but you will have to invest some time in it (currently it does not build on rawhide). I also have not used it for a long time (using deluge for bittorent tasks).
