ui/egl: fix make_context_current() callback return value 

eglMakeCurrent() returns 1/EGL_TRUE on success. This is not what the
callback expects, where 0 indicates success.

While at it, print the EGL error to ease debugging.

As with virgl_renderer_callbacks, the return value is now checked since
version >= 4:
