[PATCH 13/13] perf test: Add attr tests under builtin test command

[Jiri Olsa <jolsa@redhat.com>]

The test attr suite is run only if it's run under perf source
directory, because test attr files are not installed.

If run elsewhere, tests are ommited (notification is displayed)
and finished as successfull.
