configure.ac: correctly manage llvm auto-detection
Earlier refactoring commits changed from one, dare I say it, broken
behaviour to another. Namely:
Before, as you explicitly --enable-gallium-llvm your selection was
ignored when llvm-config was not present/detected.
Today, the "auto" heuristics enables gallium llvm regardless if you have
llvm/llvm-config available or not.
Rework the auto-detection to attribute for llvm's presence.
v2: Set enable_gallium_llvm=no when LLVM is not found.
