tools: fix docopen target
Adds to prerequisites the output file to open. Previously, this would open an out-of-date version of the file, or fail if it has not been built before.
$(apidocs_html)
is part of out/doc/api/all.html
prerequisites, it's safe use out/doc/api/all.html
as the only prerequisite here.
