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.
