The 64-bit uapi headers don't define FD_CLR and friends, so this patch updates libc/kernel/common/linux/time.h after the change b934bbec145e9e084bf48149a3a94ae3dd132157 in external/kernel-headers, then fixes <sys/select.h> to work in this new world, and removes some now-unnecessary duplication from <time.h> (with other cruft cleaned up while I'm here).
