MDBF-796: SLES - add eigen from science repository

The eigen3-devel package information:

https://software.opensuse.org/download/package?package=eigen3&project=science

Change the temporary repositories to include gpg checks from the keys
in the repo file.

This makes the eigen3-devel and judy-devel package perform gpg checks.
