Subject: [PATCH] vt.c: add missing include to fix building with uClibc

"#include <linux/serial.h>" is needed in order to build trinity

successfully with uClibc. Otherwise it would fail displaying an error

message like this one:

ioctls/vt.c:152:8: error: invalid application of 'sizeof' to incomplete

type 'struct serial_rs485'

  IOCTL(TIOCGRS485),

ioctls/vt.c:155:8: error: invalid application of 'sizeof' to incomplete

type 'struct serial_rs485'

  IOCTL(TIOCSRS485),
