xsctyaml points to incorrect libdir

[tomice]

Issue When building with yocto (zeus) and adding the meta-xilinx, as well as the meta-xilinx-tools, layers to the project, xsctyaml.bbclass will fail with the following error during do_create_yaml when target does not match native:

DEBUG: Executing python function do_create_yaml

I believe this is because the project is not inherting from native.bbclass, so native and target lib paths end up being effectively pointed to the same area. Path it is looking for in os.sys.path fsbl/2020.1+gitAUTOINC+6cbb920f4d-r0/recipe-sysroot-native/usr/lib64/python3.7/site-packages Correct path it should be set to: fsbl/2020.1+gitAUTOINC+6cbb920f4d-r0/recipe-sysroot-native/usr/lib/python3.7/site-packages

Both fsbl and device-tree will experience this since they both use xsctyaml.bbclass.

Fix Defining PYTHON_SITEPACKAGES_DIR to point to libdir_native instead of libdir in the xsctyaml.bbclass file should fix this issue.
