Minor improvements to <stdatomic.h>.

- Define __SYNC_ATOMICS in case we're using the __sync_*() API. This is
  not used by <stdatomic.h> itself, but may be useful for some of the
  intrinsics code to determine whether it should build the
  machine-dependent intrinsic functions.

- Make is_lock_free() work in kernelspace. For now, assume atomics in
  kernelspace are always lock free. This is a quite reasonable
  assumption, as we surely shouldn't implement the atomic fallbacks for
  arbitrary sizes.
