This is another case of a runtime test being needed to determine machine
capabilities before running tests. In http://trac.webkit.org/changeset/55467 I
added the ability to do this runtime check and turn on and off test directories
appropriately. It's done by running DRT with the --print-supported-features
flag. This returns a string with supported features. Currently it only includes
AcceleratedCompositing and 3DRendering, but you could add WebGL to the list.

To do this you'd have to add a acceleratedCompositingEnabled function to
WebPreferences. This would return true only if the WebGL flag is enabled on the
machine AND the hardware can support WebGL. For HW Accel we do the runtime
check in one of the platform specific files. For WebGL it would probably want
to go in GraphicsContext3D.

Once you have the pref, you'd just need to add logic to run-webkit-tests to
check for the flag and turn on or off the WebGL directories.
