eglfs: Make QEglFSWindow respect the window format

Prior to this change, eglfs code used to override the window format
with it's own format. With this change, eglfs will respect the window
format. This is useful when the application requires a surface with
alpha (for example, so that the video layer below is visible)

QEglFSHooks::surfaceFormatFor() allows the hook author to override
the context and window surface format.
