move_mrs: Disable our commit hook during the move

As GNU indent version can be different on the user system, we see some
differences during migration thas causes conflicts. Making cherry-pick
difficults to recover without breaking the style temporily. Note that
cherry-pick continuation does not allow passing the -n option to skip
the hooks.
