[Libva] [PATCH intel-driver 1/3] test: allow default surface param for create context

[U. Artie Eoff]

The driver does not require surfaces to create a context.
That is, i965_CreateContext can accept an empty render_targets
list.  Thus, make Surfaces an optional parameter to
I965TestFixture::createContext so that simple tests don't
have to bother with Surfaces if they are irrelevant to
the test case.
