perf jevents: Sort list of input files

Browse Source 
Without this, pmu-events.c would be generated with variations in
ordering depending on non-deterministic filesystem readdir order.

I tested that pmu-events.c still has the same number of lines and that
perf list output works.

This patch was done while working on reproducible builds for openSUSE,
but also solves issues in Debian [1] and other distributions.
