Install scan-build-py modules into the plain `lib` directory, without LLVM_LIBDIR_SUFFIX appended, to match the path expected by `intercept-build` executable.  This fixes the program being unable to find its modules.  Using unsuffixed path makes sense here, since Python modules are not subject to multilib.

This change effectively reverts 1334e129a39cb427e7b855e9a711a3e7604e50e5. The commit in question changed the path without a clear justification ("does not respect the given prefix") and the Python code was never modified to actually work with the change.
