Fix tst-aarch64-pkey to handle ENOSPC as not supported

Browse Source 
The syscall pkey_alloc can return ENOSPC to indicate either that all
keys are in use or that the system runs in a mode in which memory
protection keys are disabled. In such case the test should not fail and
just return unsupported.

This matches the behaviour of the generic tst-pkey.
