[travis] Horrible patchwork for Clang CMake config

In the current Debian packaging, there is a clang_shared target in the
dependency graph, but the file to realize it -- libclang_shared.so.9 --
isn't included.

This would break any CMake invocation with:

  CMake Error at /usr/lib/llvm-9/lib/cmake/clang/ClangTargets.cmake:565 (message):
    The imported target "clang_shared" references the file
       "/usr/lib/llvm-9/lib/libclang_shared.so.9"
    but this file does not exist.  Possible reasons include:
    * The file was deleted, renamed, or moved to another location.
    * An install or uninstall procedure did not complete successfully.
    * The installation package was faulty and contained
       "/usr/lib/llvm-9/lib/cmake/clang/ClangTargets.cmake"
    but not all the files it references.

By patching the clang_shared target out of all ClangTargets*.cmake
files, we can get the build going until this is fixed.
