features: accept long legacy flag names when setting features

The legacy feature flags have long names (e.g. "generic-receive-offload")
and short names (e.g. "gro"). While "ethtool -k" shows only long names,
"ethtool -K" accepts only short names. This is a bit confusing as users
have to resort to documentation to see what flag name to use; in
particular, if a legacy flag corresponds to only one actual kernel feature,
"ethtool -k" shows the output in the same form as if long flag name were
a kernel feature name but this name cannot be used to set the flag/feature.

Accept both short and long legacy flag names in "ethool -K".
