Fix tst-pkey.c pkey_alloc return checks and manual
This test was failing in some powerpc systems as it was not checking for ENOSPC return. As said on the Linux man-pages and can be observed by the implementation at mm/mprotect.c in the Linux Kernel source. The syscall pkey_alloc can return EINVAL or ENOSPC. ENOSPC will indicate either that all keys are in use or that the kernel does not support pkeys. Reviewed-by: Gabriel F. T. Gomes <gabriel@inconstante.net.br>
