Fix duplicate LC_RPATH entries on macOS Tahoe

Browse Source 
When building on macOS Tahoe, binaries were getting duplicate LC_RPATH
load commands which caused dyld to refuse to run them with a
"duplicate LC_RPATH" error that has become a hard error.

The duplicates occurred when library directories were being added
to rpath_list twice:

- from lib_directories
- from native system paths detection which includes the same dirs
