Support specifying CAN interface for testskoi_10.93.0koi_10.92.0koi/10.93.0koi/10.92.010.93.010.92.0

Add AGL_CAN_INTERFACE environment variable hook to allow specifying
the CAN interface to be used in the CAN tests.  This is required when
using an interface other than the default of "can0", since the
specific interface is needed for playback of CAN data to test binding
behavior.  The switch in AGL CI to using vcan0 on all test boards
will require this hook.
