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

This reverts commit 98a73a2ce10df46bc8d095413b415e284206836b.

Bug: 37815285
Bug: 62525809
Test: Tested with ag/2398663 and ag/2400524. Booted pixel phones,

checked the location of pro.default, verified the symlink
at /default.prop, checked a few properties via adb shell and
manually tested a few apps.
Booted to recovery mode and ran 'adb sideload' successfully.
