Subject: [PATCH 2/2] torture.txt: update the list of supported torture types

Torture types "rcu_bh" and "sched" were removed in commit "c770c82a23".
The name of torture type "rcu_busted" was changed to "busted" in commit
"b3c983142d". Two other types, "srcud" and "busted_srcud" were added in
commits "ca1d51ed98" and "2397d072f7", respectively. This patch updates
torture.txt accordingly.
