[OE-core] [PATCH v3] devtool/copy_buildsystem: adds meta-skeleton layer in the eSDK installation.

[juan.m.cruz.alcaraz at linux.intel.com]

From: Juan M Cruz Alcaraz <juan.m.cruz.alcaraz at linux.intel.com>

The eSDK installation requires the meta-skeleton layer.
The build system might use the meta-skeleton recipes as layout
to create custom recipes. An example is the recipetool script
that uses the meta-skeleton kernel recipe when creating a custom
kernel recipe.
