Subject: [PATCH] bloodlight_based.c: Create test for led.c

* Bloodlight_based.c: Test leds with led.c APIs.
* Build bloodlight_based.c by default.

Keep both tests zephyr_based (previous main) and bloodlight_based.c so
the user can select in CMakeFie which test wants to run. zephyr_based to
test leds using zephyrs APIs or bloodlight_based to test them using
bloodlight's APIs.
