configure: fix --enable-3dfx override without dga

If --enable-3dfx is specified but dga is not available then 3dfx is
disabled nonetheless. However, this disabling is not done properly,
and libvo/vo_3dfx.c is still compiled (but cannot be used). Fix.

The behavior of automatically disabling vo_3dfx despite --enable-3dfx
is itself questionable, but I'm not changing that now.
