port_fwd: Move port scanning /proc fds into struct port_fwd

Currently we store /proc/net fds used to implement automatic port
forwarding in the proc_net_{tcp,udp} fields of the main context structure.
However, in fact each of those is associated with a particular direction
of forwarding, and we already have struct port_fwd which collects all
other information related to a particular direction of port forwarding.

We can simplify things a bit by moving the /proc fds into struct port_fwd.
