lang/rust: Update to 1.22.1
Support for LibreSSL up-to 2.6.3 is now included, thus we can remove the
patches to the openssl and openssl-sys crates.
The renewed bootstrap for aarch64 was created on 11.0-RELEASE, instead
of 11.1-STABLE. It should allow it to run on all 11.x and thus fix the
build on 11.0-RELEASE. [1]
