copy_buildsystem: include layer tree during build structure creation
When buildsystem with layer structure is going to be copied, only the last
meta-XXX layer is taken.
For example, during ext_sdk bblayers creating:
layers/oe/meta \
layers/oe/meta-oe \
layers/oe/meta-networking \
layers/oe/meta-webserver \
...
It restructured meta-oe, meta-networking,... contents into meta-oe.
Recipes from meta-oe will be on the same level like meta-networking,
meta-webserver, ... .
It should take the whole meta path instead of the last one.
layers/oe/meta \
layers/oe/meta-oe/meta-oe \
layers/oe/meta-oe/meta-networking \
layers/oe/meta-oe/meta-webserver \
...
Now the directory structure is the same like during build creation.
