perf test: Fix "all PMU test" to skip parametrized events
[ Upstream commit b50d691e50e600fab82b423be871860537d75dc9 ]
Parametrized events are not only a powerpc domain. They occur on other
platforms too (e.g. aarch64). They should be ignored in this testcase,
since proper setup of the parameters is out of scope of this script.
Let's not filter them out by PMU name, but rather based on the fact that
they expect a parameter.
