Linux: Serial minor update (#1053)

- The symlink name for the PTY device is set using --my-serial-port
  making --my-serial-pty deprecated
- Replace MY_LINUX_IS_SERIAL_PTY with MY_LINUX_SERIAL_IS_PTY
- MY_DEBUGDEVICE can be used to print debug messages from MySensors
  (as it is currently in the other architectures)
- Rename SerialSimulator class to StdInOutStream
- Remove old deprecated option --my-radio
