Fix the loop condition when scanning the signal number to name table to
convert a signal number to a name. Instead of looping sizeof(size_t)
times, loop for the number of elements in the table.
This bug was masked on 64 bit-platforms, since the signal number to name
table table currently has 8 elements, which is coincidently the same as
sizeof(size_t) on 64-bit platforms. The bug becomes apparent on 32-bit
systems; only the first 4 elements of the table are checked.
