dhcp-server: T9093: allow option interface-mtu up to 16000
DHCP option 26 (Interface MTU, RFC 2132) is a 16-bit unsigned value and Kea
accepts the full range, but the CLI validator capped it at 9000 - below the
9216 used on common jumbo fabrics and below VyOS's own interface MTU maximum
of 16000.
Relax the constraint to 576-16000 and exercise a jumbo value (9216) in the
smoketest.
