  [llvm-ranlib] Change -v (alias for --version) to -V

-V prints the version information in both BSD and GNU ar/ranlib.

BSD ranlib rejects -v while -v enables verbose output in GNU ar but is
another alias for --version in GNU ranlib. The GNU ranlib behavior is
inconsistent: `ranlib -v` is different from `ar -sv`. But it's not a
major concern in practice:

* Users typically use ranlib solely for creating archive symbol tables,
  and they don't need verbose output.
* Verbose output in ranlib seems a no-op.
* GNU ar creates an archive symbol table by default. Many ranlib uses
  have been eliminated.
* Modern linkers like lld/ELF (since version 14) and mold don't rely on
  archive symbol tables anymore.

https://reviews.llvm.org/D71554 introduced -v. This patch removes it so
that `llvm-ranlib -v` and `llvm-ranlib -version` lead to errors (GNU
ranlib rejects `-version` as well). -V is added as an alias for
--version.
