Bug description:
  SRU Justification

  Impact:
  We recently backported SECCOMP_USER_NOTIF_FLAG_CONTINUE in 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1847744. On a kernel that 
supports SECCOMP_FILTER_FLAG_NEW_LISTENER but not 
SECCOMP_USER_NOTIF_FLAG_CONTINUE the selftests currently fail to compile. The 
reason is that the ifndef for SECCOMP_USER_NOTIF_FLAG_CONTINUE is placed under 
the ifndef for SECCOMP_FILTER_FLAG_NEW_LISTENER.

  Fix:
  The ifndef for SECCOMP_USER_NOTIF_FLAG_CONTINUE was placed under the
  ifndef for the SECCOMP_FILTER_FLAG_NEW_LISTENER feature. This will not
  work on systems that do support SECCOMP_FILTER_FLAG_NEW_LISTENER but do not
  support SECCOMP_USER_NOTIF_FLAG_CONTINUE. So move the latter ifndef out of
  the former ifndef's scope.

  Regression Potential:
  Limited to seccomp selftests.

  Test Case:
  Compile the selftests on a kernel that supports 
SECCOMP_FILTER_FLAG_NEW_LISTENER but does not support 
SECCOMP_USER_NOTIF_FLAG_CONTINUE and see that compilations succeeds.

  Target Kernels: All current LTS kernels with access to a 5.0 kernel.
