Let configure include `sys/if_tun.h` when testing for `netinet/if_ether.h`
to detect the Kernel/libc header conflict on musl.

After this patch, configure will correctly detect `netinet/if_ether.h` as
unusable and the subsequent compilation will not attempt to use it.

Fixes the following compatibility error:
