process.c: move sched_* parsers to a separate file

Browse Source 
* sched.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* process.c: Move sys_sched_getscheduler, sys_sched_setscheduler,
sys_sched_getparam, sys_sched_setparam, sys_sched_get_priority_min,
sys_sched_rr_get_interval, and related code to sched.c.
