797d622cc7 kernel: use connect() for some kernel tests 
Now that `connect()` works, use that for some tests rather than
exclusively using `try_connect()`.

54a8de2776 kernel: fix return_scalar and return_scalar2 
These didn't correctly set the thread status in the server when
returning a value. Instead of marking a server as runnable, it remained
in an idle state.

This correctly sets the thread status in the server, and resumes the
client.

This has been tested in Renode as well as using `cargo test`.

9a50de8b4e refactor: utra -> utralib naming 
this cleans up some namespace issues when including
the utra crate which also refers to utra::generated::utra,
and there are CONST at the crate-level, and also functions
at the module-level which need disambiguation. By naming
the crate utra-lib this saves a bit of syntatic wrangling
at the top of every file.
