linux: also import linux/in.h and in6.h from kernel-5.0

Now linux/in.h has better conflict detection with glibc's
netinet/in.h. So, let's import the headers.

Note that our code already have many workarounds for the conflict,
but in this commit does not drop them. Let's do that in the later
commits if this really helps.
