e8744fd4dc atrace: make clock & bus bw tracing optional
This change makes enabling clock tracing and bus bandwidth tracing depend on
whether the device's kernel supports these features.  If it's not supported it
will be skipped.

4b23eefd72 atrace: enable running on user builds
This change allows atrace to be run on a user build, where it is not run as
root.  Some command line options still require root, and atrace will refuse to
run if those options are specified when run as non-root.
