[OE-core] [PATCH] package_manager: Fix NoneType Object on do_populate_sdk

[Ricardo Ribalda Delgado]

PACKAGE_EXCLUDE can be not defined or empty, leading to a build error.

File: '/var/lib/jenkins/jobs/qt5022-cesium/workspace/repo/yocto/meta/lib/oe/package_manager.py', lineno: 1649, function: _create_configs
     1645:                    "Pin-Priority: %d\n\n" % (arch, priority))
     1646:
     1647:                priority += 5
     1648:
