[CLEANUP] Final cleanup of TCA Overrides

Some of the files still miss the die statement in
the first line. To be consistent, add it to every
file.

One file had a check for TYPO3_MODE === BE which
is wrong in these files because the result is
cached.

If the first hit with empty cache is done in a FE
request, a wrong result would be cached.
