feat(tvix/tracing): apply EnvFilter to all layers

Browse source 
Currently we apply the EnvFilter only to the stderr output writer.
This didn't affect any other layer, like the otlp layer, causing spans
from `h2`, `tokio_util` or other third party crate dependencies to be
always sent out via OTLP.

This changes that behaviour, applying EnvFilter to all exports, leading
to a lot less spans being exported.
