docker: replace config flags with env vars, drop docker param from deploy_chatmail

Remove change_kernel_settings/fs_inotify_max_user_instances_and_watchers
from chatmail.ini — use CHATMAIL_NOSYSCTL and CHATMAIL_NOPORTCHECK env
vars instead. deploy_chatmail() no longer takes a docker flag; deployers
check the env directly.
