hgweb: fix search {entries} to not return results of template expansion

"{entries%changelogentry}" in raw/search.tmpl was utterly wrong because
"{entries}" here was a generator yielding results of template expansion.
That's why we have a weird hack in runmap(), which I'm going to get rid of.

https://www.mercurial-scm.org/repo/hg/file/4.5.2/mercurial/templater.py#l469

We have two choices:

 a) drop "%changelogentry" from raw/search.tmpl
 b) fix "{entries}" to yield mappings

I take (b) because that's what the other log-like "{entries}" do. The
"entries" keyword is wrapped by mappinggenerator so "{entries}" without
"%searchentry" still works.
