revert back to usign autogen.sh cmdline arguments if given

This is a partial revert of ca0c54d0fe3812cec64e5c7cc83309d4397f5e0a .
Ignoring cmdline arguments if autogen.* exists is broken for several reasons:
- autogen.sh of every other package passes cmdline arguments to configure
- that's because if I was bothered to give them, I want them used
- there's no reason to prefer autogen.input now, given that autogen.input
  cannot be overwritten by autogen.sh, unlike autogen.lastrun , so there's
  no accidental loss of the switches
- running autogen.sh --foo followed by autogen.sh --bar actually runs
  configure with --foo the second time too, because the first one creates
  autogen.lastrun and the second one first complains about the cmdline
  args, then complains about autogen.lastrun, and then uses it
