  [llvm-ranlib] Handle -D and -U command line flag

I have been trying to build CheriBSD (a fork for FreeBSD for the CHERI
CPU) with LLVM binutils instead of the default elftoolchain utilities.
I noticed that building static archives was failing because ranlib is
invoked with the -D flag. This failed with llvm-ranlib since it parses
the -D flag as the archive path and reports an error that more than one
archive has been passed.

This fixes https://llvm.org/PR41707
