fbd-feedback-manager: Allow device-specific feedbackd themes

Reads the compatible list of the device and tries to find a device-specific theme file in all  directories. If no configuration is found, we fall back to a default theme file. The device-specific theme file can always be overriden by specifying the FEEDBACK_THEME environment variable
