fs_mgr: add overlayfs handling for squashfs system filesystems

/cache/overlay directory in support of overlayfs mounts on userdebug
and eng devices.  Overlayfs in turn can be capable of supporting
adb remount for read-only or restricted-storage filesystems like
squashfs or right-sized (zero free space) system partitions
respectively.

Test: compile
