slixmpp: update to version 1.8.6.

This is the last version that doesn't requires rust, and the last
version that should be compatible with Poezio 0.14.

Updating the latter to >= 0.15 will require adding new recipes for
the "maturin" python build system, as that's a build dependency for
newer slixmpp ("rustified") versions.
