glsl: use remap location when serialising uniform program resource data 

This allows us to avoid expensive string compares since we already have
a map to the pointers.

These compares were taking ~30 seconds for a single shader compile
in Godot due to it using 64,000+ uniforms.

Fixes: c4cff5f402 ("glsl: add basic support for resource list to shader cache")
