gtk: use qemu_chr_alloc() to allocate CharDriverState

The gd_vc_handler() callback is using g_malloc0() to
allocate the CharDriverState struct. As a result the
logfd field is getting initialized to 0, instead of
-1 when no logfile is requested.

The result is that when running

 $ qemu-system-i386 -nodefaults -chardev vc,id=mon0 -mon chardev=mon0

qemu duplicates all monitor output to stdout as well
as the GTK window.

Not using qemu_chr_alloc() was already a bug, but harmless
until this commit
