hlr: add TC_MSLookup_mDNS_service_GSUP_HLR_home
Request "gsup.hlr" service right after creating subscriber from the home
HLR. "TC_MSLookup_mDNS_service_other_home" is similar, but does not query
the "gsup.hlr" service. The "gsup.hlr" service has a different code path
in OsmoHLR:
- it exists without being explicitly configured and returns the IP and
port of the HLR's own GSUP server
- the request is answered, even if the subscriber is not attached to the
HLR (for Location Update via proxy)
