rust-common.bbclass: use built-in rust targets for -native builds
Rust targets have the form of 'arch-unknown-linux-gnu' while
oe's native targets are 'arch-linux-gnu', e.g. omit the vendor.
The effect this has on rust-native builds is that rust first builds
itself as stage0 for arch-unknown-linux-gnu, then builds itself
again for arch-unknown-linux-gnu, then finally uses the compiler
from second step to 'cross-compile' a compiler for 'arch-linux-gnu'.
This last step is really not necessary, and we could save 4 minutes
out of 12 if it is eliminated. Which is what this patch does
by setting the target directly to 'arch-unknown-linux-gnu'; rust's
build system then shortcuts the build process after the second step.
Given a working rust-native will be needed as early as possible in a
typical yocto build (e.g. when in a not too distant future making a
useful kernel will not be possible without rust), producing it faster
is important.
