[PATCH] Don't set BOOTPROTO= when it isn't set

[Josef Bacik <jbacik@xxxxxx>]

BOOTPROTO= is ipv4 specific, so if we don't have an ipv4 configuration this just
confuses network manager.  With the fix to pykickstart we no longer set
net.bootProto if we haven't specified one, so don't write out a blank one to the
ifcfg script.
