ref-manual: Added other argument values to set variable

The BB_DANGLINGAPPENDS_WARNONLY variable seems to be able
to be set using "1", "yes", and "true".  And, it is set using
these various methods throughout the poky metadata.  I guess it
has caused a bit of confusion so I have added the fact to the
description.
