recommended update for dhcp
This recommended update for dhcp fixes the following issues:
- Applied fix to not crash in interface discovery when the interface address is NULL (bsc#909189,bsc#870535).
- Disabled explicit gpg validation; osc source_validator does it.
- Submitted by Marius Tomaschewski (mtomaschewski)
