r/z*2mqtt: Fix device node contexts at start 

Processes running in containers only have access to a limited set of
devices, based on their SELinux type label.  The USB serial devices
exposed by the Zwave and Zigbee adapters are not labelled correctly by
default to allow them to be used in containers.

Using `chcon` to change the type label of the device before starting the
container seems to work, but seems a bit kludgy.  It would probably be
better to use a SELinux file context rule and/or a udev rule to ensure
the label is set correctly when the device node is created.
