 Disable timer-based context switches

 Summary:
 In the past, we repeatedly had problems with non-deterministic allocations
 due to stack squeezing during context switches (#4450, #8611).
 This patch adds `+RTS -V0 -RTS` as extra `RUNTEST_OPTS` for every single-
 threaded benchmark.

 Is this the right place to add the flags? Should we also do this for all
 the other benchmarks?
