net-im/pidgin-sipe: update to 1.24.0, pet portlint

Update the port to 1.24.0.

Add explicit dependencies which are installed and linked to anyway for libdbus, gstreamer1 and farstream.

Add USES=gnome.

Pet portlint by moving some entries.

Fix OCS2005 option, which had misspelled DESC and CONFIGURE_ENABLE entries, so it didn't even work.

Remove unneeded patch.
