Convert CONFIG LIB_HW_RAND to Kconfig

Browse source 
config_fallbacks.h had some logic to automatically select
LIB_RAND if RANDOM_UUID or CMD_UUID were set if LIB_HW_RAND wasn't
already selected.  By migrating LIB_HW_RAND to Kconfig, we can
remove this check from config_fallbacks.h and put it into Kconfig
