Subject: Sandbox: Handle statx and futex_time64

glibc uses statx in some more places now (e.g stat64 -> __fstatat64_time64),
but it's caught by the sandbox, which doesn't handle it and breaks.
Return -ENOSYS instead to trigger the fallback in glibc.

futex_time64 is also used internally in glibc, so handle that as well.
The signature is identical where it matters.
