[PATCH 2/4] perf test: Use shelldir to refer perf source location

[Namhyung Kim <namhyung@kernel.org>]

It uses tools/perf/include which assumes it's running from the root of
the linux kernel source tree.  But you can run perf from other places
like tools/perf, then the include path won't match.  We can use the
shelldir variable to locate the test script in the tree.

  $ cd tools/perf

  $ ./perf test dlfilter
   63: dlfilter C API                                                  : Ok
  101: perf script --dlfilter tests                                    : Ok
