linuxPackages.it87: switch upstream to Frank Crawford

This version was last touched in February 2022, as opposed to the
version we were using before, which hasn't been touched since January
2019.

I've reviewed the diff, and it all seems reasonable.  We need a newer
version of this package, because hannesha's version doesn't build with
Linux 5.18.
