Fix call to realpath with NULL second argument

If realpath() was called with a NULL second argument, it would fail in
an sb2 session. This is because when sb2 resolves the real realpath()
symbol with dlsym, it receives a pointer to __old_realpath(), which
does not allow NULL there.

Now sb2's realpath_gate malloc's a buffer if the 2nd argument is NULL,
which is what realpath() would do in this case.
