glsl: Add '.ir' extension to builtin IR files
This patch adds the extension '.ir' to all the files in src/glsl/builtins/ir/, and changes generate_builtins.py so that it no longer globs on '*' to find the files to build. This prevents spurious files (such as EMACS' infamous *~ backup files) from breaking the build.
