sched/debug: Factor out printing formats into common macros 

The printing macros in debug.c keep redefining the same output
format. Collect each output format in a single definition, and reuse that
definition in the other macros. While at it, add a layer of parentheses and
replace printf's  with the newly introduced macros.
