As trace=%sched means essentially the same as trace=/sched, as well
as trace=%clock means essentially the same as trace=/clock, I removed
both %sched and %clock; sched.test and clock.test remain but changed
to use regex match.

trace=%statfs remains because the equivalent trace=/^(.*_)?statv?fs
is not as obvious as /sched and /clock.
