Title:
  seccomp_bpf in seccomp from ubuntu_kernel_selftests failed to build on
  B-5.4

Status in ubuntu-kernel-tests:
  Fix Released
Status in linux package in Ubuntu:
  Invalid
Status in linux source package in Focal:
  Fix Released

Bug description:
  [Impact]

  Test fails to build in selftests/seccomp/seccomp_bpf.c with
  'error: storage size of ‘md’ isn’t known' due to the type
  struct seccomp_metadata not being defined for B/5.4 kernels.

  [Test case]

  Test successfully builds and test cases pass both on Bionic/5.4 and on
  Focal

  [Fixes]

  Unconditionally define struct seccomp_metadata.
  Remove linux/ptrace.h where a definition of seccomp_metadata is already being
  defined in Focal.

  [Potential regression]

  There could be future build failures if glibc headers get updated to
  include definitions of struct seccomp_metadata or if linux/ptrace.h gets updated
  to include needed definitions.
