ifconfig: Allow hostip on first non-option place after inet/inet6

Browse Source 
NuttX previous:

ifconfig eth0 10.0.0.1 [inet]
ifconfig eth0 2022::2 inet6

Try to be compatible with other systems:

Linux:
ifconfig eth0 [inet] 10.0.0.1
ifconfig eth0 [inet6] add 2022::2

FreeBSD:
ifconfig eth0 inet 10.0.0.1
ifconfig eth0 inet6 2022::2

NuttX newly supported:
ifconfig eth0 [inet] 10.0.0.1
ifconfig eth0 inet6 [add] 2022::2
