trace-cmd: 2.9.1 -> 2.9.5

Besides updating trace-cmd, this commit also switches from bundled
libtraceevent and libtracefs to their external sources. Upstream
copied those libraries to separate repositories (see
https://lore.kernel.org/linux-trace-devel/20210325172357.6e059c31@gandalf.local.home/).

Another change relates to documentation building, which upstream
reworked. We disable HTML documentation - previous versions did not
provide it too.

Finally, we enable parallel build, which is simpler if `buildPhase` is
not overridden.
