obmc-phosphor-sysd: using shell script as a dummy implementation

For evb-ast2500/evb-ast2600 machine, Python are introduced by
obmc-phosphor-sysd.py. Changing the implementation to shell script
can remove python completely from image.

Test with evb-ast2600:
```
root@evb-ast2500:~# systemctl status obmc-phosphor-sysd
* obmc-phosphor-sysd.service - Phosphor System Manager
     Loaded: loaded (8;;file://evb-ast2500/lib/systemd/system/obmc-phosphor-sysd.service/lib/systemd/system/obmc)
