perf jevents: Switch build to use jevents.py
Generate pmu-events.c using jevents.py rather than the binary built from
jevents.c.
Add a new config variable NO_JEVENTS that is set when there is no
architecture json or an appropriate python interpreter isn't present.
When NO_JEVENTS is defined the file pmu-events/empty-pmu-events.c is
copied and used as the pmu-events.c file.
