We need all available runners to be defined as subclasses of runners.core.ZephyrBinaryRunner in order to be able to look them up by name at runtime. We do this by importing them from runners.__init__. This process periodically fails when some runner or other cannot be imported, usually because it is trying to import something outside of stdlib and not handling ImportError. Rather than letting this bring down the entire Python process, catch and log the error. Sort the list again while we're here. Signed-off-by: Martí Bolívar <marti.bolivar@nordicsemi.no>
