samba-tool: Remove "domain machinepassword" command

As per Andrew Bartlett's comment:
"we should remove it.  This was originally a script to support some
interactions between samba3 and samba4, when they were in distinct build
systems.  We now can call between the two systems without difficulty at
runtime, so this command has no value."
