Torjus Håkestad 95bf85dce4 fix: add writable state directory for flake collector ...

When running nix flake metadata, nix and git need writable cache
directories. System service users have home set to /var/empty which
is read-only, causing "cannot create directories" errors.

Add StateDirectory and set HOME/XDG_CACHE_HOME environment variables
to /var/lib/nixos-exporter when flake collector is enabled.
