Subject: [PATCH] Drop USE_KERNEL_HEADERS define

This was only used for providing an option to use linux/if_packet.h
instgead of netpacket/packet.h in src/ap/iapp.c. However,
netpacket/packet.h is nowadays commonly available and hostapd already
depends on it through src/l2_packet/l2_packet_linux.c, so there is no
need to continue to provide this option for the kernel header.
