qemu_conf: Track embed root dir

Browse Source 
When initializing virQEMUDriverConfig structure we are given the
root directory for possible embed connection. Save it for future
use. While we could get it later from @uri member, it's not as
easy as dereferencing a pointer (virURIParse() +
virURIGetParam() + error reporting).
