speedup

Building shader buffer can take a lot of time in case if you have many pk3
files with shaders, as actually it grows in algebraic progression according to
number of shader files loaded. Suggested solution brings it back to linear
dependency which results in significant speedup: from ~2s to ~50ms in my case
