vzctl set: warn if there is no CT config file

People complain that if they mistype CT id on the 'vzctl set' command
line, vzctl just silently creates new configuration. This is intentional
-- you can set some parameters (like disk quota) and only then run "vzctl
create". From the other side, a warning telling there's no such config
file would be good to have.

Add it.
