sched_sedf printf formatting warnings

[Hollis Blanchard <hollisb@us.ibm.com>]

With the new sched_sedf.c, I get a whole host of these:

sched_sedf.c: In function `extraq_add_sort_update':
sched_sedf.c:183: warning: long long int format, s_time_t arg (arg 5)
sched_sedf.c: In function `__del_from_queue':
sched_sedf.c:269: warning: long long unsigned int format, s_time_t arg
(arg 4)
[...]

And since we have -Wall -Werror, the build fails.

Not sure what the right fix is here. I think Linux defined its own %z
for size_t printf arguments... Of course, there is always casting.
