perf tools: Fix pmu events parsing rule
Currently all the event parsing fails end up in the event_pmu rule, and display misleading help like: $ perf stat -e inst kill event syntax error: 'inst' \___ Cannot find PMU `inst'. Missing kernel support? ... The reason is that the event_pmu is too strong and match also single string. Changing it to force the '/' separators to be part of the rule, and getting the proper error now: $ perf stat -e inst kill event syntax error: 'inst' \___ parser error Run 'perf list' for a list of valid events ...
