Title:
  debian/tests/corosync: gfs2_jadd fails with ENOTTY for i386 package on
  amd64 kernel

Bug description:
  [Impact]

   * The gfs2_jadd command (used in debian/tests/corosync)
     fails with ENOTTY ("Inappropriate ioctl for device")
     when the i386 packages are run on an amd64 kernel.

   * The i386 kernel is gone, only amd64 is available.

   * The fix introduces the compat ioctl()s for gfs2,
     which landed in v5.5-rc1 thus not in Eoan/Focal.

  [Test Case]

   * The test steps are detailed in comment #2
     based on gfs2-utils:debian/tests/corosync,
     modified to be simpler and to fail either
     with ENOTTY (failure) or ENOSPC (success).

  [Regression Potential]

   * The previous surface for this problem is
     likely low, as i386 arch installs (which
     is not as popular/widely used as amd64
     nowadays) probably used the i386 kernel.

   * The amd64-only kernel version released
     is 5.3.0-17.18 dated 2019-10-10; gives
     ~3 month window to mid January 2020.

   * So, behavior changes could theoretically
     be seen on i386 installs with the newer
     kernel which is amd64-only, where gfs2-utils
     failed with ENOTTY and now is working fine
     or failing differently (e.g. see test-case).

  [Original Description]

  The gfs2_jadd command (used in debian/tests/corosync)
  fails with ENOTTY ("Inappropriate ioctl for device")
  when the i386 packages are run on an amd64 kernel.

  The i386 kernel has gone away, only amd64 is available:

  - The i386 kernel build is dropped as of 5.3.0-15.16:
    * Drop i386 build for 19.10 (LP: #1845714)

  - Only linux-libc-dev:i386 is still built as of 5.3.0-17.18
    * Re-enable linux-libc-dev build on i386 (LP: #1846508)

  The last passing autopkgtests for gfs2-utils:i386 are on 5.3.0-13.14 built 
for i386.
  The same kernel version built for amd64 _fails_.
  (so it's potentially user/kernel interface, or kernel-only.)
