introspect: Fix whitelist check

The whitelist is a list of well-known D-Bus names, which we then search
for the unique name we get from the method invocation - unsuccesfully.

Fix this by watching the bus for any name in the whitelist in order
to maintain a map from wel-known to unique name that we can use for
matching.
