Add MAP_SHARED_VALIDATE from Linux 4.15.
This patch adds the MAP_SHARED_VALIDATE macro from Linux 4.15 to bits/mman-linux.h and the hppa bits/mman.h. Tested for x86_64. * sysdeps/unix/sysv/linux/bits/mman-linux.h [__USE_MISC] (MAP_SHARED_VALIDATE): New macro. * sysdeps/unix/sysv/linux/hppa/bits/mman.h [__USE_MISC] (MAP_SHARED_VALIDATE): Likewise.
