Subject: [PATCH] nix: Fix registry extra attrs not being applied

This was
    mkDefault { } // filterAttrs () x

which is interpreted as
    (mkDefault { }) // (filterAttrs () x)

but the intention is
    mkDefault ({ } // filterAttrs () x)

Resulting in lastModified, rev, etc. not being included. This is
essentially just bringing this clause up-to-date with the one from
NixOS.
