perf tests: Add dwarf unwind test for powerpc
The user stack dump feature was recently added for powerpc. But there
was no test case available to test it.
This test works same as on other architectures by preparing a stack
frame on the perf test thread and comparing each frame by unwinding it.
$ ./perf test 50
50: Test dwarf unwind : Ok
