net/mpipe: remove requirement for non-upstreamed headers
net/mpipe: remove requirement for non-upstreamed headers

These headers are not part of the set that are upstreamed as part
of glibc or the kernel, and we only need a few defines from each.
The hardware is frozen so these values are not going to change
in any case.
