generic: associate a few tests with punch and zero test groups

In runtime the modified tests requires and utilizes fpunch command
of xfs_io, thus a tested filesystem shall support the feature and
running a filesystem check by "punch" group selection should include
these tests:

  * generic/176
  * generic/415
  * generic/447
  * generic/469
  * generic/562

In addition and due to the same reasons add generic/469 to zero test
group, the test already contains _require_xfs_io_command "fzero" check.
