S390: Add support for vdso getcpu symbol.
This patch adds support for symbol __kernel_getcpu in vDSO, which is available with kernel 4.5. Now sched_getcpu is using this symbol if available in mapped vDSO by defining macro HAVE_GETCPU_VSYSCALL. If not available at runtime, the former syscall is used.
