rust: Introduce arch_to_rust_arch()
On modern Power systems `uname -m` yields 'ppc64le' while the toolchain
knows the architecture as 'powerpc64le'. Provide a mapping from one to
the other to integrate with the existing architecture configuration
flags.
arch_to_rust_arch() only exists to map the OE *_ARCH variables before
any further processing, unlike arch_to_rust_target_arch() which is
specific to the internal triple handling of rust.
On Linux ppc64le systems the changes give the following config:
```
$ cat ./tmp/work/ppc64le-linux/rust-native/1.58.0-r0/targets/ppc64le-linux.json
{
"llvm-target": "powerpc64le-unknown-linux-gnu",
"data-layout": "e-m:e-i64:64-n32:64-v256:256:256-v512:512:512",
"max-atomic-width": 64,
"target-pointer-width": "64",
"target-c-int-width": "64",
"target-endian": "little",
"arch": "powerpc64",
"os": "linux",
"env": "gnu",
"vendor": "unknown",
"target-family": "unix",
"linker": "gcc",
"cpu": "generic",
"dynamic-linking": true,
"executables": true,
"linker-is-gnu": true,
"linker-flavor": "gcc",
"has-rpath": true,
"has-elf-tls": true,
"position-independent-executables": true,
"panic-strategy": "unwind"
}
```
