winemac: Fix failure to render OpenGL on macOS 10.14 (Mojave).

For programs linked against the macOS 10.14 SDK, Mojave makes all view hierarchies layer-backed. For views to which OpenGL contexts have been attached this caused a regression where they sometimes failed to render and just remain black. Updating the OpenGL context after the framework has assigned a layer to our view works around the problem. Thanks to Elviss Strazdins on Stack Overflow for the solution <https://stackoverflow.com/a/52938517/1312143>.
