kernel: use upstream patches for musl This replaces the current patches used to make the kernel headers compatible with musl with the version which was accepted upstream. This is included in upstream kernel 4.15. This was compile tested with iproute2 build on all supported kernel versions with musl and one one with glibc.

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.
