Subject: [PATCH net-next] selftests: forwarding: update PTP tcpdump patterns

Recent version of tcpdump (tcpdump-4.99.6-1.fc43.x86_64) seems to have
removed the spurious space after msg type in PTP info, e.g.:

 before:  PTPv2, majorSdoId: 0x0, msg type : sync msg, length: 44
 after:   PTPv2, majorSdoId: 0x0, msg type: sync msg, length: 44

Update our patterns to match both.
