[webkit-dev] the TestExpectations syntax has changed

[Dirk Pranke]

Assuming my changes stick, all of the TestExpectations files in the
repo have been converted to the new syntax. The old syntax is still
supported as well, but please don't use it :).

At the moment I'm chasing down some minor issues but I haven't noticed
anything massively broken. If you find issues please let me know ASAP
(preferably instead of just reverting things ;).
