sysnet: allow dhcpcd to create socket file
The dhcpcd needs to create socket file under /run/dhcpcd directory.
Fixes:
AVC avc: denied { create } for pid=331 comm="dhcpcd" name="eth0.sock"
scontext=system_u:system_r:dhcpc_t:s0-s15:c0.c1023
tcontext=system_u:object_r:dhcpc_runtime_t:s0 tclass=sock_file
permissive=0
AVC avc: denied { setattr } for pid=331 comm="dhcpcd"
name="eth0.sock" dev="tmpfs" ino=19153
scontext=system_u:system_r:dhcpc_t:s0-s15:c0.c1023
tcontext=system_u:object_r:dhcpc_runtime_t:s0 tclass=sock_file
permissive=0
AVC avc: denied { sendto } for pid=331 comm="dhcpcd"
scontext=system_u:system_r:dhcpc_t:s0-s15:c0.c1023
tcontext=system_u:system_r:dhcpc_t:s0-s15:c0.c1023
tclass=unix_dgram_socket permissive=0
