rc_conf: Add support for ifconfig_<interface>_alias[0-9]+.

Browse Source 
The interface alias allows extra IP addresses to be set on and
interface and it also allows the MAC address to be set.

Examples:
  ifconfig_em0="inet 10.10.5.33 netmask 255.255.255.0"
  ifconfig_em0_alias0="ether 10:22:33:44:55:66"
  ifconfig_em0_alias1="inet 10.1.1.111 netmask 0xffffffff"
