[nrf noup]: include: net: Align with bsdlib defines.

Adding socket family type AF_LOCAL.
Adding socket type SOCK_MGMT used in conjuction with with AF_LTE.
Adding socket protocol NPROTO_PDN to be used in conjuction with AF_LTE.
Adding socket protocol NPROTO_DFU to be used in conjuction with
AF_LOCAL.

Adding SOL_PDN and SOL_DFU socket option levels, and associated socket
option values.
