[SRU][L][PATCH v2] UBUNTU: [Packaging] introduce do_lib_rust and enable it only on generic amd64

[Andrea Righi]

BugLink: https://bugs.launchpad.net/bugs/2021605

Introduce the new variable do_lib_rust to enable or disable the
packaging of linux-lib-rust and enable it only on the generic amd64
kernel.

This allows to avoid building any kind of Rust artifact in other
kernels, except for the generic one and only on amd64.
