glsl: Initialize source_chan in opt_copy_propagation_elements.
Previously, if chans < 4, we passed uninitialized stack garbage to the
ir_swizzle constructor for the excess components. Thankfully, it
ignores that data, as it's unnecessary, so no harm actually comes of it.
However, it's obviously better to initialize it.
