[Darwin][Driver] Avoid duplicate -lc++ with -fsanitize=fuzzer (#161304)
On Darwin, duplicate `-l` options cause a warning to be printed.
Invoking clang as clang++ and using `-fsanitize=fuzzer` will cause `-lc++`
to be passed twice to the linker, causing a warning.
i.e. AddCXXStdlibLibArgs is called twice in this case:
1)
https://github.com/llvm/llvm-project/blob/19c4e86f3e8582c3f087a9fec5ac036838e58ec4/clang/lib/Driver/ToolChains/Darwin.cpp#L743
because `ShouldLinkCXXStdlib(Args)` is true.
2) The subject of this PR
We now skip adding the -lc++ argument if `ShouldLinkCXXStdlib(Args)`
(since that means the other path already added it).
