(LIBBU) API unit test for bomb.c

About
Looked into the bombs.c file, the two functions I came up with that
required testing were :
- bu_exit, which should exit the program and return the status sent as a
parameter to it.
- bu_bomb, which I tested by seeing if it gets to the end and does not
create an infinite lop.
The bu_bomb test was easy to implement, however when I tried returning
bu_exit's status, I got an error while compiling because _exit literally
kills the process.
After consultation with the mentors over IRC ( Erik, maths, mihai, and
andrei ) they suggested creating another process, a child process that
would exit, and a parent process that would get its return status. Was a
really neat trick, spent a few hours looking into functions and the whole
idea behind it, seemed really really nice, I loved it.
Attached is the diff file, please ignore modifications outside of bu_bomb
and cmakelists.txt, as these were done for other tasks and not commited to
the latest version.
Regards,
Marc
