Ian Rogers 9f116f4b81 perf tests: Add test for uncore event sorting 
Add a test for uncore event sorting matching multiple PMUs.

Uncore PMUs may have a common prefix, like the PMUs
uncore_imc_free_running_0 and uncore_imc_free_running_1 have a prefix of
uncore_imc_free_running.

Parsing an event group like "{data_read,data_write}" for those PMUs
should result with two groups:

  "{uncore_imc_free_running_0/data_read/,uncore_imc_free_running_0/data_write/},
   {uncore_imc_free_running_1/data_read/,uncore_imc_free_running_1/data_write/}"

which means the evsels need resorting as when initially parsed the
evsels are ordered with mixed PMUs:

  "{uncore_imc_free_running_0/data_read/,uncore_imc_free_running_1/data_read/,
  uncore_imc_free_running_0/data_write/,uncore_imc_free_running_1/data_write/}".
