[SDL2] function call bottleneck

The problem is that the function OSDEP_UpdateRect only does internally is call OSDEP_Flip, so hare the function is being called 2 times. See: src/shared/osdep/osd_sdl2.c , branch: master

Maybe in modern computers the speed drop is not noticeable but mine is. Moving the windows or the mouse cursor is noticeable slower.

Proposal: A conditional guard should exist for the SDL2 implementation to only call one.
