Change ipsec feature node names

ipsec4-output and ipsec6-output were conflicting with ipsec
interface names ("ipsec<id>") and vnet/interface.c autogenerated
output node ("<ifname>-output").

Changing feature names seems to be the less invasive option.
This patch also changes "input" feature names for consistency.
