[Mageia-dev] Freeze push: dhcpcd

[David Walser]

This updates to bugfix release 5.6.7.

The diff is very small, just some minor bugfixes.  Here's the changelog:
- Preserve the space in static routes on the command line. Fixes #260. 
- Check the correct interface the RAP came from before overwriting it. 
- Ensure that nooption correctly woks for routes. Fixes #254. 
- Fix potential issue if we don't want routes and we fail a decode. 

I've confirmed it builds and works fine in Cauldron.
