Check GLSL version when using ARB_shader_bit_encoding with uvec4.

Never mind, I found capabilities report for this GPU and indeed it supports
ARB_shader_bit_encoding and GLSL version 1.2 with Mesa. In the error log it
recognizes uintBitsToFloat() and suggests uvec4 as possible argument type, but
does not allow uvec4 in shader code (as uvec4 is available since GLSL 1.3). I
will send a patch. Attaching a patch here in case anyone wants to test it.
