kleink: When fstat(2)ing a file descriptor of a local communications domain
socket, fill the socket's creation time into the stat structure's st_[acm]time
fields: POSIX requires this behavior for pipe(2). N.B.: updating the
st_[am]time fields when reading/writing the pipe is neither required nor
implemented, though.
