Position the TOF cooling cross members without MANY

The twelve FTLN placements were made with the GEANT3 MANY flag, which marks a
node as overlapping its siblings. They do not overlap anything.

- Sampling points inside every MANY-placed TOF node and testing them against
  each sibling finds no sibling containing any point of an FTLN copy.
- With ONLY, TGeo's overlap checker examines these placements for the first
  time and reports no overlap in FAIA, FAIB or FAIC.
- Declared overlapping nodes in the geometry drop from 3215 to 3071; the
  material is unchanged, since the flag was not resolving anything.

This removes twelve of the sixty-six MANY placements. The remainder are real
overlaps and need the shapes to be changed.
