build: don't use Boost multi_index serialization

fanquake · fanquake · commit 0d01272cd883 · 2022-04-02T15:46:40.000+01:00
We don't use the serialilzation or archiving facilities of multi_index. So globally disable support, which gives a minor improvement in build time, i.e less preprocessing work.
