vcontainer: fix daemon mode missing shared directory for 9p

DAEMON_SHARE_DIR was referenced in the CA certificate copy and idle
watchdog paths but never assigned, causing 'cp: cannot create regular
file /ca.crt: Permission denied' when starting the daemon.

Create the share directory under DAEMON_SOCKET_DIR and register it
as a 9p mount, matching the path expected by daemon_run().
