libmatchbox: Upgrade 1.12 -> 1.13

This includes fixes for gcc 15.

License fixes were also made in the repository. The license being referred to
as MIT was in fact HPND so fix the LICENSE on the recipe accordingly.

Use the new bitbake tag functionality to verify the commit matches the tagged
version.

Trim the license checksums to the top level COPYING files now everything
is accurate.
