Subject: [PATCH] Configure datachannel target_properties for APPLE

After 7591b9695c libdatachannel stopped working with OBS on macOS[0].
XCode only resolves one level of symlinks [1]. libdatachannel
is generating two levels.

This commit updates CMake to instead use ELF Headers instead of file
names to communicate version of macOS.
