ciao-down: Remove unused password
ciao-down: Remove unused password

The cloud-init template contained a password for the user that it creates.
This password is useless as the account is created with lock_passwd set to
true.  It is just a relic from attempts to debug an early version of ciao-down.
This commit removes it.
