QEMU does not compile on an old Debian 10 system for the
following reasons:

- Several sources include recent kernel headers that are
  not provided by this system, and not listed in
  linux-headers/

- The libvhost-user.c source file ends up including a
  system kernel header, instead of the up-to-date
  standard-headers/ version that contains the right
  macro definition.

David 'Digit' Turner (2):
  Fix libvhost-user.c compilation.
  Add missing Linux kernel headers.
