Subject: cargo: Drop cross-canadian variant and fix/use nativesdk

The cargo-cross-candian variant made no sense as one version of cargo in
the SDK can work for all targets. Replace it with nativesdk-cargo instead.

Move the SDK env to rust-cross-canadian.

(From OE-Core rev: 6d6d135924eff5993736ee58ba8cc5d00ca635f3)
