glsl: Initialize samplers to 0, propagate sampler values to the gl_program

The spec requires that samplers be initialized to 0.  Since this
differs from the 1-to-1 mapping of samplers to texture units assumed
by ARB assembly shaders (and the gl_program structure), be sure to
propagate this date from the gl_shader_program to the gl_program.
