glsl: do not make sampler/image types readonly variables
In plain GLSL, sampler and image types can only be declared
uniform-qualified global variables or 'in' function parameters.
Setting the read_only flag seems quite useless because other
checks will prevent sampler/image variables to be assigned and
also because the flag is not set for atomic_uint types which are
opaque types.
This will also help for ARB_bindless_texture because samplers
and images can be assigned when they are considered bindless.
