Move creation of /data/misc/wifi and /data/misc/dhcp to main init.rc file.

mkdir /data/misc/wifi subdirectories and /data/misc/dhcp is performed
in the various device-specific init*.rc files but seems generic.
Move it to the main init.rc file.

Drop the separate chown for /data/misc/dhcp as this is handled by mkdir
built-in if the directory already exists.

Add a restorecon_recursive /data/misc/wifi/sockets.
