Update libsignal-protocol, zkgroup and curve25519-dalek

[direc85]

As @boxdot said in #whisperfish Matrix channel:

boxdot: We are quite some versions behind libsignal-protocol: using v0.32.0, last released 0.40.1
boxdot: WDYT about upgrading?
boxdot: It actually builds out of the box

Update libsignal-protocol and zkgroup to v0.40.1 and curve25519-dalek to signal-curve25519-4.1.1.

Updating tests was also necessary.

Tested on-device with Whisperfish and it seems to works fine for a few sent and received messages, both in a DM and in a group.

Neat, thanks! I'll test ASAP.

Works fine in my tests, merging! 🚀

I don't see any updated tests?

My bad. The code compiled, but push_service::tests::create_clients test failed. I fixed the pointed piece of code (configuration.rs) with updating the offending parts from the sources pointed in the comments, but didn't realize that what I fixed wasn't a test.
