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.

configure.ac: set LLVM_{C, CXX, LD}FLAGS only as needed

Earlier refactoring commits started setting the above regardless if LLVM
is used or not. Move them to the respective section to restore the
original functionality.

Since we require the preprocessor flags (includes in particular) for the
header version parsing keep those as-is. They are not used outside of
configure.ac thus should not cause any side-effects.
