glsl/nir/linker: Also remove image variables

Browse source 
If we don't, then the array shrinker may shrink them to an array of zero
images which can cause GLSL serialization to blow up but only the next
time the GLSL shader is loaded from the disk cache.

Fixes: b8ee37472d ("glsl: Use nir_var_mem_image for images")
Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/5520
