glibc: Don't inject CoreFoundation RUNPATH on Darwin

[zhaofengli]

Description of changes

ld-wrapper will otherwise attempt to inject CoreFoundation into ld-linux's RUNPATH:

[macos:nixpkgs]$ nix-build -E 'with import ./. {}; pkgsCross.aarch64-multiplatform.stdenv.cc.libc.overrideAttrs (_: { dontPatchELF = 1; })'
/nix/store/rk7m7bhka5lsn9snp2zqnmpsc1bs00sy-glibc-aarch64-unknown-linux-gnu-2.35-163
[macos:nixpkgs]$ readelf -a result/lib/ld-linux-aarch64.so.1 | grep RUNPATH
 0x000000000000001d (RUNPATH)            Library runpath: [/nix/store/9rb5qaba71mkgfgd8wfqg03cmi46xarg-apple-framework-CoreFoundation-11.0.0/Library/Frameworks]
[linux:nixpkgs]$ /nix/store/rk7m7bhka5lsn9snp2zqnmpsc1bs00sy-glibc-aarch64-unknown-linux-gnu-2.35-163/lib/
ld-linux-aarch64.so.1 
Inconsistency detected by ld.so: ./get-dynamic-info.h: 118: elf_get_dynamic_info: Assertion `info[DT_RUNPATH] == NULL' failed!

Without dontPatchELF = 1 the RUNPATH will become empty but still breaks rtld.
