skbuff: add flags to ubuf_info for ubuf setup
Currently, when an ubuf is attached to a new skb, the shared
flags word is initialized to a fixed value. Instead of doing
this, set the default flags in the ubuf, and have new skbs
inherit from this default.
This is needed when setting up different zerocopy types.
