KVM: selftests: Use proper uAPI headers to pick up mempolicy.h definitions

Drop the KVM's re-definitions of MPOL_xxx flags in numaif.h as they are
defined by the already-included, kernel-provided mempolicy.h.  The only
reason the duplicate definitions don't cause compiler warnings is because
they are identical, but only on x86-64!  The syscall numbers in particular
are subtly x86_64-specific, i.e. will cause problems if/when numaif.h is
used outsize of x86.

Opportunistically clean up the file comment as the license information is
covered by the SPDX header, the path is superfluous, and as above the
comment about the contents is flat out wrong.
