This finally makes Emacs.app with native-comp fully self-contained, no longer requiring the GCC Homebrew formula to be installed when loading *.eln files that link against /usr/local/lib/gcc/11/libgcc_s.1.dylib. By adding the signing entitlement com.apple.security.cs.allow-dyld-environment-variables, which allows dynamic library loading to be controlled via DYLD_* environment variables. It seems the lack of this was preventing Emacs from loading the bundled libgcc_s.1.dylib file from Contents/Frameworks. Fixes #53
