* New function makeFontsConf to generate a fontconfig configuration
file. Moved from NixOS.
* dot2pdf: use makeFontsConf to generate a fonts.conf containing just
the Ghostscript fonts (see NIXPKGS-29).
* dot2pdf: generate PDF directly, don't go through PS. Note that this
and using fontconfig changes the interpretation of "fontname"
attributes in dot graphs.

* Make builders unexecutable by removing the hash-bang line and
execute permission.
* Convert calls to `derivation' to `mkDerivation'.
* Remove `system' and `stdenv' attributes from calls to
`mkDerivation'. These transformations were all done automatically,
so it is quite possible I broke stuff.
* Put the `mkDerivation' function in stdenv/generic.
