Bug#1057151: clang-17: ClangTargets.cmake cannot find libclang-17.so.1

[Vincent Lefevre]

Control: reassign -1 libclang1-17 1:17.0.6-1

because the problem is actually there (and this package may be
installed even if clang-17 isn't).

This seems normal (/usr/lib/x86_64-linux-gnu/libclang-17.so.1 already
exists in libclang1-17 1:17.0.5-1). However, the symbolic link

  /usr/lib/llvm-17/lib/libclang-17.so.1

changed to

  /usr/lib/llvm-17/lib/libclang-17.so.17

in 1:17.0.6-1, and I'm wondering whether this was expected.
I suppose that this is due to one of the following changes:

   * libclang1-17: Only encode the major version in the soname. Closes: #1056126.
   * libclang1-17: Provide a symlink for the last soname with the full version.
