[libvirt] [REPOST PATCH 2/8] qemu: Introduce qemuBuildWatchdogCommandLine



Add new function to manage adding the watchdog device options to the
command line removing that task from the mainline qemuBuildCommandLine.

Also since qemuBuildWatchdogDevStr was only local here, make it static as
well as modifying the const virDomainDef.
