Fix backward compatibility with UFS1 filesystems created before June 2002

The code to handle compatibility with old filesystems exists and does
the right things. The loss of compatibility was introduced 2.5 years ago
when the superblock integrity checks were added. The problem is that the
compatibility code was being run after the new integrity checks rather
than before them.

The reason that it has taken so long to show up is because it only
affected filesystems created before UFS2 got added in June 2002 and
that had never been mounted read-write (as their superblocks would
be updated by the compatibility code if they could be written).
Hence the problem was not apparent until someone tried to mount a
pre-2002 virgin UFS1 filesystem image.

See the Pahabricator review for more details.

growfs(8): Grammar fix

Pull Request: https://github.com/freebsd/freebsd-src/pull/1056

Purge more stray embedded $FreeBSD$ strings

These do not use __FBSDID but instead use bare char arrays.

spdx: initial adoption of licensing ID tags.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Initially, only tag files that use BSD 4-Clause "Original" license.
