Add new command line argument '-a' that can be used to define the
directory where results (tarballs) are archived. Giving an empty string
disables archiving which makes sense if you store results in Git.

if a commit (to-be-tested) is defined it must be given by using '-c',
instead of a positional argument.

A shell script wrapper around oe-build-perf-test script. The purpose of
this wrapper is to act as a executor script, making it possible to run
the tests with a single command. The wrapper script initializes the
build environment, runs oe-build-perf-test and archives the results.
