[Buildsys] Tweaks to allow server-only builds

Re-include Base64, Boost and SDL2[1]

Exclude OSG but keep its headers[2]

Exclude most non-essential components and their deps

[1] SDL2 is required by the debug component
May be worth deviating from upstream by making its inclusion
conditional in the future

[2] Server component requires declarations present in the OSG headers
