vo_opengl: another GLES2 issue

Browse Source 
GLES2 randomly does not support the transpose parameter in matrix
uniform calls. So we have to do this manually. Sure it was worth to
mutilate the standard just so all these shitty SoC vendors can safe 3
lines of code.

(Obviously trying to handle all of GLES2 to GL 4.x in a single codebase
was a mistake.)
