Fix for revised file access controls of gs (bug#37719)
* preview.el.in (preview-prepare-fast-conversion): Add commands for
revised file access controls introduced after gs 9.27.
(preview-gs-restart): Use "-d" option instead of "-s" because the
former does not accept "%d" in OutputFile parameter.
Don't wrap the file name into parentheses in line with this change.
(preview-gs-flag-error): Adjust the reconstructed gs command line
argument so that it matches with the above change.
Add comments about limitations of this function.
