kselftest/arm64: tpidr2: Adjust to new clone() behaviour

In order to fix an ABI problem, we recently changed the way that a
clone() syscall manipulates TPIDR2 and PSTATE.ZA. Historically the child
would inherit the parent's TPIDR2 value unless CLONE_SETTLS was set, and
now the child will inherit the parent's TPIDR2 value unless CLONE_VM is
set.

Update the tpidr2 test for the new behaviour.
