feat(base): Make ObservableMap::stream works on `wasm32-unknown-unk…

…nown`.

This patch updates `eyeball-im` and `eyeball-im-util` to integrate
jplatte/eyeball#63. With this new feature, we
can have a single implementation of `ObservableMap` (instead of 2: one
for all targets, one for `wasm32-u-u`). It makes it possible to get
`Client::rooms_stream` available on all targets now.
