linux: Quiet some noisy logs when logging to file (#13260)

Thorsten Ball created 2 years ago

zbus, naga, and some parts of blade are pretty noisy at the INFO level.
zbus especially dumps large debug dumps into the logs.

So on Linux, when logging to a file, we reduce that noise. That means
one still gets the full firehose when doing `RUST_LOG=info cargo run`,
but not in the logs.

- N/A
