This update for suse-module-tools fixes the following issues:

- Blacklist isst_if_mbox_msr driver because uses hardware information based on
CPU family and model, which is too unspecific. On large systems, this causes
a lot of failing loading attempts for this driver, leading to slow or even
stalled boot (bsc#1187196)
