[PATCH:makedepend 2/4] Remove fallbacks for Imake configuration, assume autoconf

[Alan Coopersmith]

For the original 6.9/7.0 release, we supported using either autoconf or
imake to generate configuration.  For releases after that, we're only
supporting autoconf, so no longer need to check & fall back to imake.
