util: add find_subdomain_by_sid()
This function takes domain SID (doesn't have the last component) or object SID (have all components) and returns subdomain. The subdomain is found by comparing domain->domainid with the SID. E.g. domain SID: S-1-5-21-3940105347-3434501867-2690409756 object SID: S-1-5-21-3940105347-3434501867-2690409756-513 Resolves: https://fedorahosted.org/sssd/ticket/2034
