Can't mini_uring rely on the kernel header like
selftests/net/io_uring_zerocopy_tx.c does?  That test doesn't depend on
liburing either.  I ask because this will be the third copy of these
definitions that we're gonna need to keep in sync (kernel, liburing and
here). Given this is only used for selftests, we better avoid the
duplication.
