Update to newever version

yubioath-desktop: prefix QML2_IMPORT_PATH

gnome2.gtkdoc -> gtk-doc

ccls: 0.20181225.8 -> 0.20190301

bigwig-studio2: 2.4.3->2.5

…file.

54baa53 added support for the special
attribute "haskellPackageOverrides" to the Nixpkgs config file to which users
could add their Haskell-specific package overrides. That mechanism has since
then been replaced by the more general "packageOverrides", which has
subsequently been replaced by Nixpkgs overlays, which have recently been
extended for Haskell-specific needs by the "haskell.packageOverrides"
attribute.

"haskellPackageOverrides" was never documented anywhere, so it seems unlikely
that its removal is going to affect anyone.
