fix(index): remove noenable_verify_root

[12:31:10] <marineam>	 philips: shouldn't --noenable_rootfs_verification be removed?
[12:34:27] <philips>	 marineam: we don't use verity right now
[12:35:21] <marineam>	 philips: whether we actually do verify that flag controls whether the rootfs can be mounted rw, and mounting rw seems like a bad thing to mix with updates right?
[12:35:35] <marineam>	 *whether or not*
[12:35:45] <philips>	 marineam: oh, I didn't realize that part was working
[12:35:54] <philips>	 marineam: ok, that is fine with me
[12:36:01] <philips>	 marineam: I will dump that part
