hwdb: use curl instead of wget, and regenerate patch after successful update

hwdb: use curl instead of wget, and regenerate patch after successful update

libcurl is already our build dependency, so using curl reduces the deps
a bit, and curl also has a more modern codebase.

Regenerating the patch makes it more likely that the patch will apply
in the future.

Also, update URLs which return 302 to the new location.

(Patch suggested by Igor Gnatenko.)
