[Libguestfs] [PATCH] configure: Don't define _FORTIFY_SOURCE.

[Richard W.M. Jones]

We routinely test the upstream code by running everything under
valgrind, and in any case _FORTIFY_SOURCE is usually defined by
downstream Linux distros and we can leave the optimization vs safety
decision to them.
