rust: Fix crossbeam-utils for arches without atomics

crossbeam-utils tries to use the triplet to look up whether the target
supports various forms of atomics. We use TARGET_VENDOR and not "-unknown"
in the target case which means this fails and breaks platforms like mips
and powerpc 32 bit. Add a patch to handle TARGET_VENDOR in this case.
