Jamil 54e1a79a50 fix(ios): portal connectivity and tunnel setup (#1927)
This PR fixes issues with the iOS client connecting to the portal and
setting up the tunnel.

- portal IPv6 unique-local prefix typo
- Use `rustls-webpki-roots` instead of `rustls-native-roots` for tokio
tungstenite since the latter [only supports macOS, Linux, and
Windows](https://github.com/rustls/rustls-native-certs) while the former
seems to work on all platforms(?)
- Remove Multipath TCP entitlement for iOS since it's not relevant for
us.

@conectado After this is merged, we _almost_ have a working tunnel on
iOS. I believe the error we're hitting now is the 4-byte address family
header that we need to add and strip from each packet written to / read
from the tunnel. See below log for sample output when attempting to
connect to the `HTTPbin` resource:
