scripts/poky-qemu: Improve tmp layout assumption

If someone has changed TMPDIR in local.conf to a non-standard location, the
poky-qemu script currently doesn't handle this and assumes if BUILDDIR is set,
$BUILDDIR/tmp will exist.

Its simple to check if this exists and if not, to ask bitbake where the
directory is so this patch changes the code to do that.
