Clean up Package_html_static.mk

For ONLINE_HELP, apparently the source helpcontent2/help3xsl/index.html goes to
instdir/help/index.html while the source helpcontent2/help3xsl/index2.html goes
to instdir/help/$PRODUCTVERSION/index.html.

And for !ONLINE_HELP, apparently both source files (index.html and index2.html)
went to instdir/help/index.html, and the second one (index2.html) apparently
happened to win.  Cleaned that up, so that only the source
helpcontent2/help3xsl/index2.html goes to instdir/help/index.html.

Whether that's all as intended, or some of that is junk, I don't know.

(Also sorted list of files lexicographically, for easier comparison with `ls`
output.)
