Jim Mussared 9be0623d4c shared/libc/string0: Don't deref args for n==0 case. 
C99 says that strncmp has UB for either string being NULL, so the
current behavior is technically correct, but it's an easy fix to handle
this case correctly.

7.1.4: "unless explicitly stated otherwise in the detailed
description... if an argument to a function has ...null pointer.. the
behavior is undefined".

7.21.1: "Unless explicitly stated otherwise in the description of a
particular function in this subclause, pointer arguments on such a call
shall still have valid values, as described in 7.1.4".

Also make the same change for the minimal version in bare-arm/lib.c.

This work was funded through GitHub Sponsors.
