Ana Hobden 867f894289 Populate $XDG_DATA_DIRS with appropriate folder from Nix profile
On non-NixOS systems, the default `nix` install does not populate the
`$XDG_DATA_DIRS`. This populates it and enables things like bash-completion
and `.desktop` file detection for `nix` profile installed packages.
