perf tests: Fix Track with sched_switch test for hybrid case
commit 1da1d60774014137d776d0400fdf2f1779d8d4d5 upstream.
If cpu_core PMU event fails to parse, try also cpu_atom PMU event when
parsing cycles event.
Fixes: 43eb05d066795bdf ("perf tests: Support 'Track with sched_switch' test for hybrid")
