nixos/dconf: refractor

Browse source 
remove `with lib;`
profiles option now accepts packages in addition to paths.
profiles option is no longer internal.
cfgDir definition has been inlined.
pulled GIO_EXTRA_MODULES inside mkif.
removed pointless comments with section headings.
defined profiles are now turned into package, allowing to simplify the db update logic.
