[libvirt] [PATCH 10/12] src: add check for termios.h and conditionally include it

[Daniel P. Berrangé]

The GNULIB termios module ensures termios.h exists, but
this is not neccessary and libvirt doesn't use any of its
functionality on platforms where it is missing. It is
thus sufficient to conditonallyinclude termios.h
