[PATCH RFC v2 13/15] hazptrtorture: add READERS4 and READERS0 torture configs

[Kunwu Chan]

Add READERS4 and READERS0 configs to cover reader-active and
reader-free synchronize paths.

Both use the PREEMPT baseline and hazptr-stack torture type,
with four readers for READERS4 and no readers for READERS0.
