nheko: add identicons support

Nheko has support for identicons. There is a checkbox in the settings of
nheko but it wasn’t clickable because the dependency (“qt-jdenticon”
plugin) was missing.

This change adds “qt-jdenticon” as a new package (Qt plugin) and as a
dependency for Nheko. This package is maintained by Nheko team.
