[ptxdist] [PATCH] kernel/perf: enable jevents

[Lucas Stach]

perf jevents are metrics that build on top of the raw perf events and
can provide much more insight at a glance than the raw numbers. Enable
them by default as the only dependency is host-python to generate the
C files to build into the perf target tool from the json description.
