virsysinfo: Define and use auto cleanup func for virSysinfoDef properly

Browse Source 
What we are using really is heap allocated structure rather than
stack allocated. And for that it's better to use g_autoptr() +
G_DEFINE_AUTOPTR_CLEANUP_FUNC() combo, as Glib documentation for
g_auto() reads:

  This is meant to be used with stack-allocated structures and
  non-pointer types. For the (more commonly used) pointer
  version, see g_autoptr().

This will be even more visible, when virSysinfoDefPtr type is
gone. Stay tuned.
