trace-events: Fix attribution of trace points to source

trace-events: Fix attribution of trace points to source

Some trace points are attributed to the wrong source file.  Happens
when we neglect to update trace-events for code motion, or add events
in the wrong place, or misspell the file name.

Clean up with help of cleanup-trace-events.pl.  Same funnies as in the
previous commit, of course.  Manually shorten its change to
linux-user/trace-events to */signal.c.
