cmake: install ceph-disk to /usr/sbin

* add keyword "INSTALL_SCRIPT" to distutils_install_module(), so we can
  override the install path of ceph-disk script.
* refactor the Distutils.cmake module a little bit, the ${option}
  variable out lives the CODE snipplet. so we need to reset it
  at the beginning.
