Fix webmin netatalk paths

[benjamink]

Fixes #1304

[rdmark]

@benjamink Was it only the binaries that were in a different location from what the netatalk2 module expected?

For your reference, this is what we have as the default config right now: https://github.com/Netatalk/netatalk-webmin/blob/branch-netatalk2/config

When I set this script up, my goal was to align with the default locations that you get when using the netatalk install script in easyinstall.sh. Before making any changes, I want to double check that the afpd binaries get installed in /usr/local/sbin and not /usr/sbin with a fresh install.

Confirmed the default location:

dmark@macuntu:~/piscsi$ stat /usr/local/sbin/afpd
  File: /usr/local/sbin/afpd
  Size: 2399160   	Blocks: 4688       IO Block: 4096   regular file
Device: fc02h/64514d	Inode: 1610085     Links: 1

I don't think the restart is required here. The updated config should be read immediately by the webmin module.

[benjamink]

Ah, ok. Removed.

This is stylistic suggestion for readability, but when operating on strings with slashes in them, I recommend using a different delimiter for the s command. I think I used @ elsewhere in this script.

Agreed. Fixed.
