Fix FileIo.cpp gcc 8 compile warning about strncpy use without copying the null-termination [-Wstringop-truncation]

Authored by elexis on Aug 7 2019, 5:25 PM.



-Wstringop-truncation was introduced in gcc 8 and it is triggered for one line in the code.
It's not broken, since the \n is intentionally omitted. The warning shall vanish without the warning being disabled though.

Test Plan

Ensure that the code behavior is the same:

This can be achieved by backing up a PMP file, overwriting it in atlas, seeing that the contents didn't change.
Fun fact: If one passes a number smaller than three, then the according substring is copied and the rest of the 4 bytes are zeroes.
