igc: fix LEDS_CLASS dependency

When IGC is built-in but LEDS_CLASS is a loadable module, there is
a link failure:

x86_64-linux-ld: drivers/net/ethernet/intel/igc/igc_leds.o: in function `igc_led_setup':
igc_leds.c:(.text+0x75c): undefined reference to `devm_led_classdev_register_ext'

Add another dependency that prevents this combination.
