linux scripts: Respect $CARGO_TARGET_DIR (#13830)

https://doc.rust-lang.org/cargo/reference/environment-variables.html

Some people (myself included) set this variable to have a single
directory to clean up (or whatever reason one might have for having a
single `target` directory). This changes the linux scripts to respect
that
