Set VNC password from xenstore.

Upstream doesn't appear to have a way to set the password other than
from the monitor, so we introduce this which is a bit messy.

When upstream's new option/config parsing is merged, we should make a
patch for upstream with a config option to read the password out of a
file or fd, and use that.
