[PATCH weston 4/9] tests: Add weston-test-runner for weston test extension tests

[U. Artie Eoff]

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

Wayland's test-runner uses a forking method to run each test
in its own address space.  This technique works well, thus, do
the same technique for Weston test extension tests.
