Can't set DYLD_FALLBACK_LIBRARY_PATH env var while other variables can be set correctly

[onsails]

Describe the bug
I'm trying to define DYLD_FALLBACK_LIBRARY_PATH environment variable but it's not being picked up by a devenv shell.

To reproduce

Put into devenv.nix:

env.DYLD_FALLBACK_LIBRARY_PATH = "${pkgs.llvmPackages.libclang.lib}/lib";
env.DYLD = "${pkgs.llvmPackages.libclang.lib}/lib";

in devshell:

❯ env | grep DYLD
LD_DYLD_PATH=/usr/lib/dyld
DYLD=/nix/store/4s2s478cgc19jclm1zg2anjd0kh549nb-clang-16.0.6-lib/lib

as you can see, DYLD_FALLBACK_LIBRARY_PATH is absent

Make sure to include full logs and what you expected to happen.

Version

Paste the output of $ devenv version here or tell us if you're using flakes.

❯ devenv version
devenv 1.3.0 (aarch64-darwin)

IIRC there's a SIP restriction that prevents this variable from being passed across exec boundaries.

Try exporting it in enterShell.
