Since commiteedc81b6ef
("fwd, conf: Probe host's ephemeral ports"), we might need to read from /proc/sys/net/ipv4/ip_local_port_range in both passt and pasta. While pasta was already allowed to open and write /proc/sys/net entries, read access was missing in SELinux's type enforcement: add that. In passt, instead, this is the first time we need to access an entry there: add everything we need. Fixes:eedc81b6ef
