Add a target that generates a log file for running metric_test.py and
make this a dependency on generating pmu-events.c. The log output is
displayed if the test fails like (the test was modified to make it
fail):
```
TEST /tmp/perf/pmu-events/metric_test.log
F......
======================================================================
FAIL: test_Brackets (__main__.TestMetricExpressions)
----------------------------------------------------------------------
Traceback (most recent call last):
File "tools/perf/pmu-events/metric_test.py", line 33, in test_Brackets
self.assertEqual((a * b + c).ToPerfJson(), 'a * b + d')
AssertionError: 'a * b + c' != 'a * b + d'
- a * b + c
? ^

----------------------------------------------------------------------
Ran 7 tests in 0.004s
FAILED (failures=1)
make[3]: *** [pmu-events/Build:32: /tmp/perf/pmu-events/metric_test.log] Error 1
```
However, normal execution will just show the TEST line.
This is roughly modeled on fortify testing in the kernel lib directory.
Modify metric_test.py so that it is executable. This is necessary when
PYTHON isn't specified in the build, the normal case.
Use variables to make the paths to files clearer and more consistent.
Committer notes:
Add pmu-events/metric_test.log to tools/perf/.gitignore and to the
'clean' target on tools/perf/Makefile.perf.
