[CI/CD] Add github actions to replace Travis

Due to new limitations for open-source projects on Travis we are
switching to GitHub actions.

* Notes about system site-packages

We had many problems with accessing system python packages on Travis for
libtorrent and GTK and the problems are harder on Github since there is
no more access. For now copying the python libtorrent binary into the
deluge source is the workaround. There is a pip package that could be
used in future.

Fixed failing tests with libtorrent 1.2 which required a non-zero length
file in torrent and workarounds for async alert delay.
