doc: remove llvm-config search from configure documentation

As of 4dd29b6833, we no longer attempt to locate any other llvm-config
variant than plain llvm-config in configure-based builds; update the
documentation accordingly. (For Meson-based builds, we still use Meson's
LLVMDependencyConfigTool [0], which runs through a set of possible
suffixes [1], so no need to update the documentation there.)
