base-files: support oneshot leds properly.

oneshot trigger configurations for LEDs are created, but the on/off
timing configurations are ignored.  generate_config is correctly creating
oneshot configs, but the later led script doesn't recognise the trigger
details.

Fixes: c0c3f2d4c9 leds: support oneshot as well as timer triggers
