[CI] Use libtorrent pypi install

Up until now, the linux installation source of libtorrent was launchpad,
because there was no other source, and we wanted a debug version of lt.

With pypi wheel versions now available use lt in the requirements.txt
file.

Closes: https://github.com/deluge-torrent/deluge/pull/364
