net-im/nheko: update to 0.9.0, latest upstream
This pulls in an update to mtxclient (which then needs coeurl...).
E2E encryption is now fully supported (but not audited). There is
VOIP support which is switched off right now because our gstreamer
seems to be too old.
security/olm: Update to 3.2.6, latest release
It looks like I do not have the right bits for portscout here,
so didn't get notifications of new versions. Release notes are at:
https://gitlab.matrix.org/matrix-org/olm/-/releases#3.2.6
There are many updates. Dependent ports mtxclient (needed a compile-
patch) and nheko bumped so they pick this up.
