When generating the extended SDK, there is a copy step where this class
goes through the layers and other stuff that have been copied to
generate the SDK. The corebase; ie. the folder that contains the core
layer 'meta' is treated in a special way. Unfortunately in our tree, we
have:
In populate_sdk_ext's copy_buildsystem, the heuristic to determine which
element of the list returned by copy_bitbake_and_layers is corebase is
fooled by such layout.
In copy_bitbake_and_layers, corebase is already handled specifically and
reliably, so we should let that function tell us which folder is
corebase instead of trying to determine it.
To do so, change the return type of copy_bitbake_and_layers to a tuple
that contains (corebase, copied_layers). It also simplifies the code on
the caller side.
