Fix "Text file busy" on reinstall while service is running

Browse Source 
cp truncates the destination in place, which fails with ETXTBSY when
the binary is currently executing (e.g. running update.sh while the
systemd service is active). Copy to a temp file and mv it into place
instead - mv is a rename within the same filesystem, which the
kernel allows even for a running binary.
