oeqa/runtime/cases/multilib.py: fix test_file_connman skipping logic
The test_file_connman should be executed only when 'lib32-connman' is
installed and 'connman' is not installed.
When lib32-connman and connman are both installed, the /usr/sbin/connmand
could be from connman or lib32-connman, depending on the installation
order. What we want to check is the connmand command from lib32-connman,
so we need to make sure that connman is not there to cause chaos.
