Missing time.h header declaration results in compile-time warnings

[xandark]

I got three warnings when running make under a fresh Raspbian Stretch install, which complained about a missing declaration for one function: nanosleep().

These were solved by inserting:

#include <time.h>

into a2joy.c, a2joymou.c, and a2joypad.c.

Then making resulted in a clean, warning-less build and gave me a little more confidence that everything was okay :)
