Introduce libiconvOrNull and libiconvOrGlibc

Browse source 
One can use these attrs instead of custom 'if ... then libiconv else null'.
This way we can maintain the correct 'if ... then' check in one place.

NB: I don't know what is the correct condition, so I use stdenv.isLinux. Feel
free to fix this.
