nixos module: support NixOS user packages install

When using the NixOS module we cannot guarantee that the Nix store
will be writable during startup. Installing the user packages through
`nix-env -i` will fail in these cases.

This commit adds a NixOS option `home-manager.useUserPackages` that,
when enabled, installs user packages through the NixOS

    users.users.<name?>.packages

option.

Note, when submodule support and external package install is enabled
then the installed packages are not available in `~/.nix-profile`. We
therefore set `home.profileDirectory` directly to the HM profile
packages.

When using Home Manager as a NixOS submodule it is now
possible to install packages using the NixOS
users.users.<name?>.packages
option. This is enabled by adding
home-manager.useUserPackages = true;
to your NixOS system configuration. This mode of operation
is necessary if you want to use 'nixos-rebuild build-vm'.
