bgpd: Modify attr->flag to be 64 bit

With the some current bgp drafts the Attribute number has
surpassed 32.  Which is a bit unfortunate in that we keep
track of the attributes via a bitfield based on the attribute #.

For the moment since I am not aware of Attribute #'s being
greater than 64, convert the flag to 64 bit and allow the
bit shifting to know about it.
