Subject: [PATCH] rust/log: set the log level with a pure Rust function

Make sure the log level is setup with a pure Rust function, so
when it is set, its set within the address space of the caller.

This is important for Rust plugins where the Rust modules are not
in the address space of the Suricata main process.
