xfree86: parser: drop obsolete token enum values

These have been forgotten on some major cleanup back almost two decades ago.
(Daniel dropped a lot of dead code, which already had been removed earlier
but merged back accidentially).

Didn't look further back on where exactly they had become obsolete - being
unused for decades should be enough justification for dropping.
