Revert "net: Use samba default command line arguments."

This reverts commit fb262f79fab00374023e59476e8d05a1015a7041
and related commits c36031778e1983ddb11d3e1fcab35e738dbf94bc
72fd5fa6bb78a054fad5e5ebe19a0c0387a7d45b and
38cd0e086f50ce54d88a19aa5a6803469af90489

This change caused more trouble than it solved. We need to do this differently.
Reverting so we don't accidently release this.
