gl/cocoa: set the view to use for drawing by the context

It avoids to draw to an invalid buffer.
Withtout this the default frame buffer is undefined:
glBindFramebuffer (GL_FRAMEBUFFER, 0)

Visually you could see some white frames at the beginning
when lunching videotestsrc ! glimagesink

With OpenGL Profiler from XCode you could see some
GL_INVALID_FRAMEBUFFER_OPERATION for the first frames
