packet/bmp: Obsolete policy argument for BMPPeerHeader
According to "draft-evens-grow-bmp-local-rib", the L flag in the Peer
Flags is NOT used for the locally sourced routes and the F flag is
defined into the same bit.
This patch removes "policy" argument and add "flags" argument for
BMPPeerHeader and NewBMPPeerHeader in order to distinguish which flag
is set (the L flag or the F flag).
Then introduce IsPostPolicy() func to show if the L flag is set or not.
