kernel: enable CONFIG_LEDS_TRIGGER_HEARTBEAT

The heartbeat trigger is used by luci-mod-system, which is installed
as a part of the standard luci package set. It seems the LED trigger
will be required quite often, so let's enable it by default.

This increases uncompressed kernel size by about 100 bytes on ath79/generic.
