[CMake] Add lib to swift host libraries link directories

bnbarham · bnbarham · commit 4186d628e142 · 2023-03-15T16:55:01.000-07:00
Our libraries have a `LC_LINKER_OPTION` for eg. `-lswiftLLVMJSON`.
This is resolved (probably just based on the actual libswiftLLVMJSON.a
added to the link command) by ld, but not by lld. Add in a link
directory so that these libraries can be found.
