memset_explicit tests: Fix signature check

[Bruno Haible]

Building a testdir on Android, I get this warning:

../../gltests/test-memset_explicit.c:26:1: warning: incompatible function 
pointer types initializing 'void (*)(void *, int, size_t)' (aka 'void (*)(void 
*, int, unsigned int)') with an expression of type 'void *(void *, int, 
size_t)' (aka 'void *(void *, int, unsigned int)') 
[-Wincompatible-function-pointer-types]

This patch fixes it.
