netlink: specs: rt-link: convert bridge port flag attributes to u8

Browse Source 
A number of IFLA_BRPORT_* attributes are documented in the rt-link spec
as having the "flag" type, i.e. a payload-less NLA_FLAG attribute whose
meaning is presence-only. This does not match the kernel, which emits
these attributes with nla_put_u8() and validates them as NLA_U8 in
br_port_policy[]. The values are not mere presence flags but carry a u8
payload (0/1).

Convert these bridge port attributes from "flag" to "u8" so the spec
reflects the actual wire format.
