Add configuration file over-ride mechanism
Reusing the windowmanager on the cluster demo platform requires modifications to the layers.json, areas.db, etc. configuration files. To allow this without breaking potential shared package feeds by building two versions, add a mechanism to allow over-riding the configuration files present in the widget with files in the directory /etc/xdg/windowmanager. Affected code has been refactored to use a new common configuration file path determination helper function to reduce duplication. Bug-AGL: SPEC-1805 Change-Id: Ia3e1af0703794079f9537b934b124788129c045c Signed-off-by: Scott Murray <scott.murray@konsulko.com>
