wpa_supplicant: Use PF_LOCAL instead of PF_INET*

Browse source 
Using a local socket circumvents the issue of needing any Internet
protocol (PF_INET or PF_INET6) support.
We only use interface ("i" group) ioctls on this socket so we can get
away with using PF_LOCAL instead of requring any Internet protocol
(PF_INET or PF_INET6) support on the system. This simplifies the
patch from 8c7149c73f.
