[PATCH v1 1/2] perf test: Add an 'import perf' test shell script

[Ian Rogers <irogers@google.com>]

The 'import perf' test needs to set up a path to the python module as
well as to know the python command to invoke. These are hard coded at
build time to be build a directory and the python used in the build,
which is less than desirable. Avoid the hard coded values by reusing
the existing shell script python setup and determine a potential built
python module via the path of the perf executable.
