Early rule loading - livebox issue.

Early rule loading - livebox issue.

[Issue#]        SSDWSSP-298
[Bug/Feature]   Livebox issue fix.
[Cause]         Missing rules while showing homescreen.
[Solution]      Add early-rules loading.
[Verification]  Compile. Install at least 2 widgets,
                then check if /opt/etc/smack-app-early/accesses.d/WRT file contains
                a "livebox.web-provider ~APP~ rwx" rule for every app.
                Then uninstall one app and check if rule for this app is gone.
                Others rules should remain untouched.
