Expose the inner tool's --configitem FOO=bar, added by:
83095fe9 configkernel: add --configitem and --verbose

This allows a vng user to build a kernel thusly:

  vng -b --config <partial-or-full-conf> --configitem FOO=bar

The --configitems are set after defaults and all --config's, so
they're handy for scripting in a last set of build variations.

  # prevent face-palm errs
  vng -b --config <frag> --configitem FOO=y
  vng -b --config <frag> --configitem FOO=n
  vng -b --config <frag> --configitem FOO=m

  # help uname -r help us
  vng -b --config <frag> --configitem FOO=m \
      --configitem KMEMLEAK=y --configitem LOCALVERION=-wleak
