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.
