Hack around wifi_legacy_hal.h transitive include bug. am: 7715d50e

#include <wifi_system/interface_tool.h>

// HACK: The include inside the namespace below also transitively includes a

// bunch of libc headers into the namespace, which leads to functions like

// socketpair being defined in android::hardware::wifi::V1_1::implementation::legacy_hal.

// Include this one particular header as a hacky workaround until that's fixed.

#include <sys/socket.h>
