Restore functionality of --sysroot on FreeBSD after b18cb9c47

  After b18cb9c47, clang would sometimes prefer the host C++ includes
  (e.g. in /usr/include/c++/v1) before those specified via --sysroot.
  While this behavior may be desirable on Linux, it is not so on
  FreeBSD, where we make extensive use of --sysroot during the build of
  the base system.  In that case, clang must *not* search outside the
  sysroot, except for its own internal headers.

  Add an override addLibCxxIncludePaths() to restore the old behavior,
  which is to simply append /usr/include/c++/v1 to the specified
  sysroot.  While here, apply clang-format to the FreeBSD specific
  toolchain files.

  Fixes PR44923.
