sched/debug: Make CONFIG_SCHED_DEBUG functionality unconditional

Browse Source 
All the big Linux distros enable CONFIG_SCHED_DEBUG, because
the various features it provides help not just with kernel
development, but with system administration and user-space
software development as well.

Reflect this reality and enable this functionality
unconditionally.
