`ROOT_APPEND_LIBDIR_TO_INSTALL_RPATH` assumed that `install_dir` is always relative to `CMAKE_INSTALL_PREFIX` when computing the relative path to `CMAKE_INSTALL_FULL_LIBDIR`. However, some build environments (e.g. Fedora or Nix) pass an absolute `CMAKE_INSTALL_LIBDIR`, which results in an incorrect relative path. Fix this by detecting whether `install_dir` is absolute and using it directly as the base directory when computing the relative path. (cherry picked from commit e2df120)
