sdbus++: remove 'path' type

The type 'path' is ambiguous because it really isn't file-system
paths but dbus object paths.  A while ago 'object_path' was added
for more clarity and 'path' has been deprecated.  All uses of 'path'
in phosphor-dbus-interfaces has been updated and it is a trivial fix
for any other downstream users.  Removing 'path' so that the older
typename is no longer used.
