exec: Allow loading x86_64 executables on x86_64
Since we don't support mixing i386 and x86_64 binaries on the same
system (as running them requires different build-time gnumach
configurations), the exec server can simply require the binary being
loaded to have been built for the same architecture as the exec server
itself.
