Add overflow check for INPUT_EVENT_POS_MIN

* src/keyboard.c (INPUT_EVENT_POS_MIN): Don’t assume (-1 -
INPUT_EVENT_POS_MAX) fits into ptrdiff_t.  This fixes a
purely-theoretical problem that cannot occur on two’s-complement
arithmetic.  The Solaris 10 compiler still complains incorrectly,
but oh well.
