net/keepalived: fix kmod-macvlan dependency

If the option 'use_vmac' is selected in a keepalived config and
kmod-macvlan is not installed then keepalived raise an error.

  Netlink: error: Not supported, type=(16), seq=1510647577, pid=0
  vmac: Error creating VMAC interface vrrp.42 for vrrp_instance xxx!!!

Add 'kmod-macvlan' to the package dependency list fixes this error.
