xfs_scrub: fix licensing and copyright notices [v24.5]

Fix various attribution problems in the xfs_scrub source code, such as
the author's contact information, out of date SPDX tags, and a rough
estimate of when the feature was under heavy development.  The most
egregious parts are the files that are missing license information
completely.
