uek-rpm: config-debug: Turn off torture testing by default

The OL7 debug kernels are configured with multiple torture tests
built into the kernel, and consequently are all of them
trying to run by default during boot. This is a waste
of time and kWs.

This can be observed by the following
messages in the system log during boot:

 kernel: spin_lock-torture:--- Start of test [debug]: nwriters_stress=4 nreaders_stress=0 stat_interval=60 verbose=1 shuffle_interval=3 stutter=5 shutdown_secs=0
 kernel: spin_lock-torture: Creating torture_shuffle task
 kernel: spin_lock-torture: Creating torture_stutter task
 kernel: spin_lock-torture: torture_shuffle task started
 kernel: spin_lock-torture: Creating lock_torture_writer task
 kernel: spin_lock-torture: torture_stutter task started
 kernel: spin_lock-torture: Creating lock_torture_writer task
 kernel: spin_lock-torture: lock_torture_writer task started
 kernel: spin_lock-torture: Creating lock_torture_writer task
 kernel: spin_lock-torture: lock_torture_writer task started
 kernel: spin_lock-torture: Creating lock_torture_writer task
 kernel: spin_lock-torture: lock_torture_writer task started
 kernel: spin_lock-torture: Creating lock_torture_stats task
 kernel: spin_lock-torture: lock_torture_writer task started
 kernel: spin_lock-torture: lock_torture_stats task started
 kernel: torture_init_begin: Refusing rcu init: spin_lock running.
 kernel: torture_init_begin: One torture test at a time!

Better to compile these as modules to make them readily
available for testing if need be, than to run them all
at boot which does not seem to make sense at all judging
from the above log.
