[SRU][J][PATCH 1/2] UBUNTU: SAUCE: selftests: net: veth: use short form gro for ethtool -K

[Massimiliano Pellizzer]

BugLink: https://bugs.launchpad.net/bugs/2136734

The veth.sh selftest fails on systems with older ethtool versions
(e.g., ethtool 5.4 on Focal) because the ethtool -K command does not
recognize 'generic-receive-offload' as a valid feature name.

This causes test failures like:
	ethtool: bad command line argument(s)
	For more information run ethtool -h
	- gro flag with GRO on                  fail - expected on found off

Fix by using the short feature name 'gro'
which works across all ethtool versions.
