fat-binary-m1: use arm64e for dylib, but not for executable

Browse Source 
according to research done by @malash, the proxychains4 binary
itself isn't allowed to use system-internal arm64e mode; but
it's possible to add it as a 3rd architecture to the shared
library (.dylib), and then even inject it into system binaries
like /usr/bin/curl, which didn't work since the introduction
of SIP.

therefore, we now create the dylib with all 3 archs, but the
launcher only with arm64 and x86_64.

closes #453
