vo_opengl: fix operation on GLES 2.0 

GLSL in GLES 2.0 did not have line continuation in its preprocessor.
This broke shader compilation. It also broke subtitle rendering in
vo_rpi, which reuses some of the OpenGL code.

Line continuation was finally added in GLES 3.0, which is perhaps the
reason why ANGLE accepted it.
