rcutorture: Disable tracing to permit Tasks Rude RCU testing

Now that the KPROBES, TRACING, BLK_DEV_IO_TRACE, and UPROBE_EVENTS
Kconfig options select the TASKS_TRACE_RCU option, the torture.sh tests
of enabling exactly one of the RCU Tasks flavors fail.  This commit
therefore disables these options to allow this testing to succeed.
