tools/perf: Turn strlcpy() into a __weak function
The strlcpy() feature check slows every build unnecessarily - so make it a __weak function so it does not have to be auto-detected. If the libc (or any other library) has an strlcpy() implementation it will be used - otherwise our fallback is active.
