clutter-1.0: add ptest

Upstream has reworked installed-tests, use them for ptest.
Default output format for tests is not TAP, add patch to generate TAP output.
Run tests with gnome-desktop-testing-runner, which understands TAP output.

Tested on nuc with core-image-clutter and core-image-weston.

Reminder that for "pure" wayland (e.g. core-image-weston) you need to "export CLUTTER_BACKEND = wayland" to get past setting the DISPLAY variable expected for X11 backend.

(See patch refrenced from OE-core rev: 1c3beda0015da9a0fec2581af7645c9ea122c7e3)

Modifies do_configure to inject DRV_CFLAGS variable into wpa_supplicant/.config which is then included during make of drivers.
