449eff02d2 Add futimes, futimesat, and lutimes.
Spotted these while cleaning up <sys/cdefs.h> --- if we remove __USE_XOPEN2K8,
libchrome decides you "must" have futimes. Adding the missing functions (all
just alternative interfaces to utimensat(2) system call) lets us clean up
without breaking anything.

7f54348f30 Loosen up sys_time.gettimeofday.
We've seen it take 1146us on Nexus 9 (which did have exceptionally slow
system calls).

f8fcfbc85a Move away from the __ARCH_WANT_SYSCALL_NO_AT system calls.
Modern architectures only get the *at(2) system calls. For example,
aarch64 doesn't have open(2), and expects userspace to use openat(2)
instead.
