vo_opengl: utils: some more minor shader string building optimization

Instead of reallocating almost all of the shader string several times
per pass, build it into a fixed buffer that will be reallocated as
needed.

While this still uses a linear search and full comparison of the shader
text, this will compare the shader's string length first before doing a
full comparison as a nice side effect. (That's also why the fragment
shader is compared first - it's more likely to be different for
different cache entries than the vertex shader stub.)
