cmake function patch

Hello,

I built LLVM 12 from the release/12.x branch on OpenBSD 6.9, the output of the
command `llvm-config --system-libs` is wrong, I get this:

    -lpthread -lm -lz.so.5.0 -lcurses.so.14.0

It should be this:

    -lpthread -lm -lz -lcurses

I've found that it can be fixed by changing the get_library_name cmake function
(https://github.com/llvm/llvm-project/blob/release/12.x/llvm/cmake/modules/GetLibraryName.cmake)
with the attached patch.

I don't know if this is the proper way to fix this, I've only been able to test
it on openbsd and linux.
