UBUNTU: SAUCE: seccomp: fix SECCOMP_USER_NOTIF_FLAG_CONTINUE test

BugLink: https://bugs.launchpad.net/bugs/1849281
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.
