Add a kselftest that exercises the RDS getsockopt() paths converted to
the getsockopt_iter() / sockopt_t callback:

- RDS_RECVERR and SO_RDS_TRANSPORT, which return their int value through
  copy_to_iter() and report the written length in opt->optlen.

- RDS_INFO_*, which obtains the userspace buffer pages with
  iov_iter_extract_pages() (including a non-zero starting page offset)
  and lets the info producers copy the snapshot in under a spinlock.
