perf tests: Check that complex event name is parsed correctly 

Extend regression testing to cover case of complex event names enabled
by the cset f92da71280 ("perf record: Enable arbitrary event names
thru name= modifier").

Testing it:

  # perf test
   1: vmlinux symtab matches kallsyms                       : Skip
   2: Detect openat syscall event                           : Ok
   3: Detect openat syscall event on all cpus               : Ok
   4: Read samples using the mmap interface                 : Ok
   5: Test data source output                               : Ok
   6: Parse event definition strings                        : Ok		<===!
   7: Simple expression parser                              : Ok
...

Committer testing:

  # perf test "event definition"
   6: Parse event definition strings                        : Ok
  # perf test -v 6 2> /tmp/before
