Bug description:
  A number of new *time64 syscalls are introduced in newer kernel series
  (>=5.1.x):

  403: clock_gettime64
  404: clock_settime64
  405: clock_adjtime64
  406: clock_getres_time64
  407: clock_nanosleep_time64
  408: timer_gettime64
  409: timer_settime64
  410: timerfd_gettime64
  411: timerfd_settime64
  412: utimensat_time64
  413: pselect6_time64
  414: ppoll_time64

  In particular utimensat_time64 is now used inside glibc>=2.31

  In turn ubuntu with has trouble running docker images of newer distros.
  This problem affects libseccomp<2.4.2, ie bionic (lts), and eoan, but not 
focal.

  See a similar report at Fedora:
  https://bugzilla.redhat.com/show_bug.cgi?id=1770154

  A solution could be to backport the related changes from 2.4.2
  similarly to what happened for the statx whitelisting
  (https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1755250).
