The real libkern.h now uses "long long" that eVC has no clue about.

Instead of polluting libkern.h with ifdefs introduce our own private
copy.  Since AFAICT we only need it for libsa/ufs.c which only
includes it for the strlen() prototype, trim it to provide just that
for now.

We cannot just #include <string.h> (the WinCE one) here, as that pulls
in a lot of unrelated stuff, e.g. defines for limits that collide with
machine/limits.h
