Fix critical lens distortion bug in libmv after rB3a7d62cd1f5e.

Current libmv_modal_solver_test fails since rB3a7d62cd1f5e.

It appears that the issue is caused by the insertion of the new OFFSET_K4 parameter,
as, if camera intrinsics are not required to implement/use all of those deform
parameters, they absolutely have to keep order (values) matching those defined
in bundle.cc, otherwise `PackIntrinisicsIntoArray` and `UnpackIntrinsicsFromArray`
will mangle them around.
