weston-init: shore up touch calibrator installation

- Avoid use INI_UNCOMMENT_ASSIGNMENTS to handle [libinput] section,
  since that's done in meta-freescale layer which can create a race
  condiction depending on the order of meta-freescale and
  meta-toradex-demos in BBLAYERS.
- Add a sanity check to ensure "calibration_helper" and
  "touchscreen_calibrator" to be added to weston.ini only when they are
  not already in it by deleteting them in advance. This can prevent a
  force do_install (bitbake install -f) to add them in more than once.
