perf probe: Fix event namelist to duplicate string
Fix event namelist to duplicate string. Without duplicating, adding
multiple probes causes stack overwrite bug, because it reuses a
buffer on stack while the buffer is already added in the namelist.
String duplication solves this bug because only contents of the
buffer is copied to the namelist.
