tor+healthcheck: fix healthcheck for multiple services

Fixes #6013.
This commit fixes the Tor healthcheck that would previously fail if
there were multiple hidden service registered.
In the controller, we only need to know that our service is contained in
the list of active services. But we can't do a string equality check
since there might be multiple services, comma separated.
