ioctl_tty.2: Fix information about header include file
Header file termios.h contains incompatible definitions for linux ioctl
calls. Correct definitions are exported by header file linux/termios.h but
this file conflicts with sys/ioctl.h header file (required for ioctl()
call). Therefore include direct asm header file asm/termbits.h which
contains compatible definitions and structures for ioctl calls.
