roachtest: temporarily disable network partition mutator

Dev-Kyle · Dev-Kyle · commit 0cda1d68b4f3 · 2025-08-07T18:40:42.000-04:00
The current methodology for ensuring failure injections don't intersect
is a little hacky, so this change temporarily disables network
partition's until this is better handled.
