perf expr: Fix "has_event" function for metric style events

Browse source 
[ Upstream commit 6dd76680b9 ]

Events in metrics cannot use '/' as a separator, it would be
recognized as a divide, so they use '@'. The '@' is recognized in the
metricgroups code and changed to '/', do the same in the has_event
function so that the parsing is only tried without the @s.
