x/arch/arm64: refine objdump test to avoid false alarm

TestObjdumpARM64* is fuzzy test which randomly generates instructions for
decoder and uses host objdump to compare results. Some old objdump wrongly
decodes ldur*/stur*/prfum as ldr*/str*/prfm. Refine allowedMismatchObjdump
function to allow the mismatches to avoid false alarm.

Fixes golang/go#21486
