Removing deprecated parameters from smb.conf

[chelobarik]

The dietpi-software script generates a samba configuration file smb.conf with outdated parameters. The testparm verification script displays the following warnings:

# testparm
Load smb config files from /etc/samba/smb.conf
lpcfg_do_global_parameter: WARNING: The "syslog only" option is deprecated
lpcfg_do_global_parameter: WARNING: The "syslog" option is deprecated
lpcfg_do_global_parameter: WARNING: The "encrypt passwords" option is deprecated

This fix removes deprecated parameters and replaces them with current ones.

Thanks, makes sense. But this disables file logging, when not appending file as well. I would actually vote for that, but then we should further increase the syslog log level. "2" implies authentication failures, AFAIK, so that probably makes sense, too.

Okay let's merge this. I'll run some test whether the log level should be increase to 2, but generally we want to minimise logs to /var/log anyway (for default setup).
