rcuscale: Add CONFIG_PREEMPT_DYNAMIC=n to TRACE01 scenario

It is no longer possible to build a kernel with a preemption-disabled
RCU without use of CONFIG_PREEMPT_DYNAMIC=n. This commit therefore
adds CONFIG_PREEMPT_DYNAMIC=n to the rcuscale torture type's TRACE01
scenario file.

torture: Remove RCU_FAST_NO_HZ from rcuscale and refscale scenarios

All of the rcuscale and refscale scenarios that mention the Kconfig option
CONFIG_RCU_FAST_NO_HZ disable it. But this Kconfig option is disabled by
default, so this commit removes the pointless "CONFIG_RCU_FAST_NO_HZ=n"
lines from these scenarios.
