[Cygwin] Don't use version script for Cygwin target

[kikairoya]

Cygwin is a COFF platform and does not support version-script.
I guess I should use LLVM_HAVE_LINK_VERSION_SCRIPT here, but I don't know why this is not currently the case.

[jeremyd2019]

LGTM

[jeremyd2019]

It looks like LLVM_HAVE_LINK_VERSION_SCRIPT is used in libclang and AddLLVM.cmake but not in clang-shlib or llvm-shlib
