hypnotix: 3.7 -> 4.0

https://github.com/linuxmint/hypnotix/compare/3.7...4.0

Since `~/.cache/hypnotix/favorites` is created by `usr/bin/hypnotix` the
shell script, we need to actually install it. As a consequence, we also
need to fix shebang for `usr/lib/hypnotix/hypnotix.py`, adding python3 as
buildInputs should do the work.
