[ Reason ]
Provide current information about national radio regulations to the
Linux Wi-Fi stack.

[ Impact ]
Users may accidentally configure Wi-Fi hardware to use channels or
power levels that are not permitted, or may be unable to use channels
that are permitted.

[ Tests ]
- The signatures on regulatory.db are checked against the kernel trust
  list by an autopkgtest test case.
- The database itself is identical to the version in unstable, and
  currently identical to the upstream version.

[ Risks ]
The package is fairly trivial.  The only risk I see is that the new
database could conceivably differ from the actual regulations in a
more serious way.

[ Checklist ]
  [X] *all* changes are documented in the d/changelog
  [X] I reviewed all changes and I approve them
  [X] attach debdiff against the package in (old)stable
  [X] the issue is verified as fixed in unstable

[ Changes ]
This is a backport from testing/unstable, because every suite should
get the latest rules.

Upstream changes:
- Updated the regulatory database (db.txt) following various national
  radio regulatory changes.
- Regenerated the binaries and signatures (regulatory.bin,
  regulatory.db, regulatory.db.p7s) and checksum (sha1sum.txt) from
  db.txt.

Debian changes:
- Regenerated my signature for the regulatory database
- Removed Build-Depends: python-is-python3, which lintian flags as an
  error.  Reapplied the patch that was previously used to make
  upstream scripts run with Python 3.  I wouldn't have bothered to do
  this for trixie, but this is a backport from forky.
- Disabled the uscan CI job, which would fail on trixie and doesn't
  matter
