test: hermetic XDG homes for the suites that attach outside e2e

throughput, xversion, wan, bench and soak's persistence leg all attached
against the developer's real $XDG_STATE_HOME, so every run appended a
throwaway socket to ~/.local/state/mux/wall — 139 tiles, 135 dead, and
muxweb dialing all of them at start. e2e and agent already isolated;
now every suite does.
