[PATCH weston] Add --with-tests-environment option to configure

[U. Artie Eoff]

From: "U. Artie Eoff" <ullysses.a.eoff at intel.com>

The --with-tests-environment allows one to specify a custom tests
environment script.  This is useful for customizing and/or
normalizing test result output to whatever format necessary
(e.g. xml).
