qemu-dm: open char devices "file:..." with O_APPEND

The "file:..." character open method is used by serial and parallel
ports, to divert the output to a file (and these devices never produce
any input).  This is like a logfile, and so should be opened for
append.

In qemu-xen-unstable, this is used only for the qemu stderr by libxl.
