filesystem: extend support for FreeBSD (#2902)

* extend support for FreeBSD

* Check if FS exists with `fstyp` if `blkid` fails to find FS signature
  (fix a potential data loss)
* Add support for FreeBSD special devices (character devices).
* Add support for FreeBSD native fstype (UFS).
* Update DOCUMENTATION accordingly.

* add/update integration tests

* Add tests for `fstype=ufs` on FreeBSD.
* Run `remove_fs` tests (`state=absent`) on FreeBSD.
* Run `overwrite_another_fs` tests on FreeBSD.

* add a changelog fragment

* fix indentation

* restrict new tests to regular files

* fix typo

* fix searching of providersize (block count)

* add '-y' option to growfs command

* remove references to versions older than the collection itself

* bump version adding new feats to 3.4.0

* reformat *collection* and *version added* for better DOCUMENTATION parsing

* skip tests for FreeBSD < 12.2

* run tests for FreeBSD >= 12.2

* re-enable tests for FreeBSD < 12.2 and give it a try with group1

* util-linux not available on FreeBSD < 12.2
