[efi] Veto the Itautec Ip4ConfigDxe driver 

The Ip4ConfigDxe driver bug that was observed on Dell systems in
commit 64b4452 ("[efi] Blacklist the Dell Ip4ConfigDxe driver") has
also been observed on systems with a manufacturer name of "Itautec
S.A.".  The symptoms of the bug are identical: an attempt to call
DisconnectController() on the LOM device handle will lock up the
system.

Fix by extending the veto to cover the Ip4ConfigDxe driver for this
manufacturer.
