uapi/if_ether.h: prevent redefinition of struct ethhdr
commit 6926e041a8920c8ec27e4e155efa760aa01551fd upstream.
Musl provides its own ethhdr struct definition. Add a guard to prevent
its definition of the appropriate musl header has already been included.
glibc does not implement this header, but when glibc will implement this
they can just define __UAPI_DEF_ETHHDR 0 to make it work with the
kernel.
