rust: pass correct target to bindgen on Usermode Linux
Usermode Linux uses "um" as primary architecture name and the underlying
physical architecture is provided in "SUBARCH".
Resolve the target architecture flags through that underlying
architecture.
This is the same pattern as used by scripts/Makefile.clang from which
the bindgen flags are derived.
[ David says:
(...) this is enough to get Rust-for-Linux working with gcc under
64-bit UML on my system.
