s390x assembly pack: extend s390x capability vector. Extend the s390x capability vector to store the longer facility list available from z13 onwards. The bits indicating the vector extensions are set to zero, if the kernel does not enable the vector facility. Also add capability bits returned by the crypto instructions' query functions.
