Remove some images that were previously used on the old homepage of Clang static analyzer (`clang-analyzer.llvm.org`) but became unused since then.

Among the four removed images, `scan_build_cmd.png` was copied to a different location within the repository (and the RST-based docs use it from that location); while the other three are not referenced at all (`git grep` produces no results).
