Michael Tremer 37fe3658a0 samba: Add helper script to pipe password
It is complicated to set the password in the C helper binary.

Therefore it is being set by a helper script.

This is still not an optimal solution since the password might be
exposed to the shell environment, but has the advantage that shell
command injection is no longer possible.

Fixes: #12562
