gnulib: temporary hacks to deal with glibc libio.h removal

Browse Source 
GLibc deprecated libio.h in 2.27 and has removed it in current
code that will become 2.28. The latter is now in Fedora rawhide
and this change breaks gnulib which mistakenly still relies on
these ancient symbols. Add a local hack for gnulib until a
proper fix is available upstream.
