Jin Yao c7a3828d98 perf tests: Add test for PMU aliases 
A perf uncore PMU may have two PMU names, a real name and an alias.

Add one test case to verify that the real and alias names have the same
effect.

Iterate sysfs to get one event which has an alias and create an evlist
by adding two evsels. Evsel1 is created by event and evsel2 is created
by alias.

Test asserts:

  evsel1->core.attr.type == evsel2->core.attr.type
  evsel1->core.attr.config == evsel2->core.attr.config
