Mount system as read-only by default

Mounting system as rw can prevent future OTA updates. The purpose
of this patch set is to prevent TWRP from mounting sytem as rw on
the first boot. Device maintainers should update their twrp.fstab
files on these devices to include an additional line:
/system_image emmc /dev/block/../system

This line will allow TWRP to create a raw system image backup to
ensure that the user can return to an original state for future
OTA updates.
