devel/breezy: update to 3.3.8

I managed to bluntly patch out all use of Rust (which was useless
anyway). I commented out some lines in the Makefile that were there to
support Rust. These can be used to test it; and also when in the future
Rust no longer can be avoided (which seems likely to happen).

Upstream changes: unknown; doc/en/release-notes/brz-3.3.txt mentions
nothing beyond 3.3.5.
