Antonio Niño Díaz e8a16c6f53 Don't generate output file if overlay isn't found ...

Previously, the output file was opened before trying to open the
overlay. Because of this, rgblink generated an empty output file if the
overlay couldn't be opened.

Now the overlay is opened (and checked) before the output file, so the
output file is only generated if the overlay is found.
