handle htobe32 et al. on glibc systems with a non-Linux kernel

This fix copies over an updated #if clause from libknot's
src/contrib/endian.h.

This should resolve:

See also discussion about this same problem in libknot from a couple
years ago:

    https://bugs.debian.org/840460

I note that contrib/wire.h in knot-resolver is out of sync with
src/contrib/wire.h (and src/contrib/endian.h) from libknot.  I don't
know whether there's any upstream preference for keeping these in sync
in some more reliable way than manual comparisons.  For now i'm just
providing a narrow fix for the specific problem.
