Docker: Support trace-cmd

Build trace-cmd as part of the docker image, so that trace tests can be
used. Unfortunately the version provided by distributions is a little old
and has bugs. It also does not support specifying the time base for the
trace, which is required to convert microseconds to nanaseconds.
