bitbake-layers: flatten: warn the user if output structure is incorrect 

If you flatten layers that have different directory structures you may
not end up with a usable layer in the output directory - some files
won't be picked up by BitBake.

To try to avoid this problem, once flattening has completed, get the
BBFILES entries that correspond to the layer from which the output
layer's conf/layer.conf came from, and check through all of the
.bb/.bbappend files in the output directory to see if any will not be
referred to by BBFILES in the output layer. If any are found, show a
warning to the user.

(Bitbake rev: 8e4dc97614f2022855143b49d18795ca0352b237)
