avrdude: rewrite expression

* Use stdenv.mkDerivation instead of composableDerivation.
  stdenv.mkDerivation is the current coding standard and is easier to
  read (IMHO).

* Remove the 'parportSupport' flag because it doesn't do anything.
  (Parallel port support is still enabled.)

* Remove unneeded --disable-dependency-tracking flag to ./configure; our
  default builder does that already.

* Fix documentation build. But it is still disabled (by default),
  because texLive is such a big dependency. There is always the man
  page.

* Update 'meta' attributes
