[connman]: Fixed Scan Issue
Description: In following use case, ConnMan always perform the ssid based scan and unable to find the new AP's. a. Connect with any AP (Normal or Hidden) b. Disconnect with AP c. After this, ConnMan always perform the SSID based scan. Impact: Tizen Device is unable to scan new AP's. Reason: In Tizen, ConnMan configure the "BackgroundScanning" flag as false because background scan feature is implemented in net-config module. Due to this reason, I have added patch to sync-up the ConnMan scan implementation with net-config background scan feature.
