Optional fallback on virtual subsystem
BZ: 122982
When the PFW starts, it loads subsystems using their corresponding
plugins. If a requested plugin is not found, the start fails. This is a
problem, as for host, plugins are not compiled.
Add an option to fallback on virtual subsystem if a plugin is not found
during load.
