vavoom: Nuke versions 1.32 and 1.33

vavoom-1.32 is the last version to have a software renderer, but is very
buggy, so much so, that it seems that vanilla Doom linedef actions are
confused (or something like that). It was masked in ::fauxmight for that
reason.
vavoom-1.33 fixes some bugs, but is utterly pointless since vavoom-scm
works just fine.
With the exlib, these versions can be resurrected with little effort if
necessary anyway.
