freedroidrpg: remove build-time flags embedding into binary

Noticed extra -dev dependencies in the runtime closure.

Before the change:

    $ nix path-info -rsSh $(nix-build -A freedroidrpg) | nl | tail -n1 | unnix
    158  /<<NIX>>/freedroidrpg-0.16.1 228.2M  808.1M

After the change:

    $ nix path-info -rsSh $(nix-build -A freedroidrpg) | nl | tail -n1 | unnix
    141  /<<NIX>>/freedroidrpg-0.16.1 228.2M  450.7M
