trinity: 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),
-----------------------------------------

Backporting an upstream patch to fix this problem.
