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

- Use /etc/modules-load.d/sg.conf for sg driver autoloading (bsc#1036463)
- modsign-verify: support for parsing PKCS#7 signatures (bsc#1111300, bsc#1105495)
- Fix logic for unsupported modules (bsc#1111183)
- Add udev rule 81-sg.rules to make sure the sg module is always loaded (bsc#1036463)
- Use path dependency that is not parsed by obs to ensure we are not
pulling systemd everywhere
- Grep os-release and not deprecated SuSE-release
