[PATCH] selftests: add missing include linux/sockios

[Alakesh Haloi <alakesh.haloi@xxxxxxxxx>]

Including <linux/sockios.h> fixes the following compiler warning

timestamping.c: In function ‘printpacket’:
timestamping.c:261:19: error: ‘SIOCGSTAMP’ undeclared (first use in this function); did you mean ‘SIOCGSTAMPNS’?
   if (ioctl(sock, SIOCGSTAMP, &tv))
                   ^~~~~~~~~~
                   SIOCGSTAMPNS
