hlr: add TC_MSLookup_mDNS_service_other_home

Send an mslookup mDNS request to the home HLR, asking about a service
that is not "gsup.hlr". Hence the "_other" in the test name, service
"gsup.hlr" has different code paths, and related tests will be added in
follow-up patches.

This is the first test using MSLookup_mDNS_Emulation, so add related
test infrastructure.
