CLOUDSTACK-10220: Configure IPv4 alias on VR regardless of IPv6 (#2396)
IPv4 and IPv6 are two different protocols and the presence of IPv6
in a network does not mean that IPv4 aliases/multiple subnets should
not be configured or supported by the VR.
This if-statement was written almost 5 years ago in a attempt to
add IPv6 support to CloudStack but was never fully implemented.
