Load default prop from /system/etc/prop.default

Browse source 
/default.prop is moved to /system/etc/prop.default for full Treblized
devices. Modifies property_service to load it from there first.
In recovery mode, the file is renamed as /prop.default. This path is
tried if /system/etc/prop.default is not available.

Bug: 37815285
Test: Tested with ag/2419001. Booted pixel phones, checked the location
      of prop.default, verified the symlink at /default.prop, checked a
      few properties via adb shell and manually tested a few apps.
      Booted to recovery and ran 'adb sideload' successfully.
