0244416aacbad03e4ebe8f2c95c7861a318916ea security: restrict abis in bitcoind.service (Charlie)

Pull request description:

  [As noted here](https://www.freedesktop.org/software/systemd/man/systemd.exec.html#MemoryDenyWriteExecute=), it's a good idea to pair `MemoryDenyWriteExecute=true` with `SystemCallArchitectures=native` because `MemoryDenyWriteExecute` can be circumvented in some operating systems which support multiple ABIs like x86/x86-64.
  This helps restrict the possible application binary interfaces (ABIs) that can be used when running bitcoind through systemd, reducing the attack surface area.
