python3-scapy: upgrade 2.6.1 -> 2.7.0

Bump to the v2.7.0 tag. Rebase the ptest ICMPv6 skip patch: upstream
added a "needs_root" tag to the "Sending and receiving an
ICMPv6EchoRequest" test's tag line in test/regression.uts, so the
"skipped_ptest" tag now needs to be appended after "needs_root"
rather than replacing the whole line. With this rebase both hunks
apply with offset only (no fuzz).

Build-verified: python3-scapy builds and packages (including
-ptest) successfully.
