Fix ioctl issues on DragonFly BSD and FreeBSD 

* Include the correct headers on DragonFly BSD and FreeBSD.

* Use UTF-8 characters to draw border on Linux.

* Use ioctl 'KDGETLED' to get the keyboard LED states, which is supported
  on both Linux and BSD.

* Use macros 'LED_NUM' and 'LED_CAP' instead of hard-coded magic numbers.

NOTE:
This patch only allows 'ly' to build fine on DragonFly BSD and FreeBSD
(other *BSD not tested), and more works are needed to make 'ly' working
fine on BSD.
