[PATCH v1]: perf tests: check that complex event name is parsed correctly

[Alexey Budankov]

Extend regression testing to cover case of complex event names enabled 
by the patch "perf record: enable arbitrary event names thru name= modifier".

tools/perf/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
