tools lib traceevent: Change tag string for error
The traceevent lib is used by the perf tool, and when executing
perf test -v 6
it outputs error log on the ARM64 platform:
running test 33 '*:*'trace-cmd: No such file or directory
[...]
trace-cmd: Invalid argument
The trace event parsing code originally came from trace-cmd so it keeps
the tag string "trace-cmd" for errors, this easily introduces the
impression that the perf tool launches trace-cmd command for trace event
parsing, but in fact the related parsing is accomplished by the
traceevent lib.
This patch changes the tag string to "libtraceevent" so that we can
avoid confusion and let users to more easily connect the error with
traceevent lib.
