conf: Rename and expose virDomainChrSourceDefPath

It comes very handy to have source path for chardevs. We already
have such function: virDomainAuditChardevPath() but it's static
and has name not suitable for exposing. Moreover, while exposing
it change its name slightly to virDomainChrSourceDefGetPath.
