The issue preventing the gVisor benchmark from working has magically
been resolved by us doing nothing. Yay! Reenable the benchmark.
... Except the startup benchmark, which does `runsc run`, doesn't work
on the builders. Womp womp. Disable just that benchmark for now; any
coverage here is useful.
Fixes#51445.
Updates #67508.
