update: configuradorfnmt: 5.0.2 -> 5.0.3 (#695)

I haven’t been able to find the changelog of this release, so I did a
manual diff between this and the previous release (5.0.2).

`wcurl
https://descargas.cert.fnmt.es/Linux/configuradorfnmt_5.0.{2,3}.amd64.deb`

and using `diffoscope` to locate the differences.

Changes seem restricted to updated certificates and a bunch of minor
bugfixes, consistent with a minor release.
