tests: Make it possible to run the unit tests with EGL_SURFACELESS

For some reason it is not possible to create a normal EGL context when
a mesa software renderer is used as a backend, and hence the unit tests
will all fail. Make it possible to force a surfaceless EGL context by
specifying the environment variable

   VRENDTEST_USE_EGL_SURFACELESS=1
