flow_dissector: set encapsulated control flags from tun_flags
Set the new FLOW_DIS_F_TUNNEL_* encapsulated control flags, based
on if their counter-part is set in tun_flags.
These flags are not userspace visible yet, as the code to dump
encapsulated control flags will first be added, and later activated
in the following patches.
