Make rustup tmp dir writable and and add rust channel env var
This MR:
- bumps the image version
- adds the
CLICKABLE_RUST_CHANNEL
env var needed for Clickable to know the installed channel - makes
/opt/rust/rustup/tmp
writable to avoid permission errors with the rust builder
This is a prerequisite of clickable!441 (merged)
