Don't generate output file if overlay isn't found

Browse Source 
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.
