sanity-meta-virt.bbclass: add class for bbappend files checking

Browse Source 
Add a new class, sanity-meta-virt.bbclass, to check for whether necessary
settings are available for bbappend files in this layer to be effective,
and warn users if not.

In addition, a variable SKIP_SANITY_BBAPPEND_CHECK is added to enable users
to explicitly skip the checking to avoid unwanted warnings.
