Ship the border filler in the Windows installer, and count what is staged

The installer smoke test asserted seven model files, the number on the
day it was written; models/face has since gained the eye-state trio's
companions and the int8 detector forms, and the run on f71d7ba failed
with thirteen installed. The test now expects as many files as
package.sh's directories hold, so the next model needs no edit here.

package.sh also stages models/inpaint, which the APK and the Arch
package already carry and the Windows build did not: without
migan-512.onnx the panorama's border fill has no model on Windows.
xfeat needs nothing, it is embedded in the binary. windows.md §5.2
lists the result.
