This turned out to be a mistake in the way I was using apol.

First, all the necessary Booleans have to be set (I had missed enabling
httpd_enable_cgi).  For analyzing policy.conf, the allow rule can be
found using Policy Rules > TE Rules, enabling Include Indirect Matches,
with the Source Type set to httpd_t and Target Type set to
httpd_sys_content_t:

(5597) allow  httpd_t  httpdcontent : file  { create ioctl read getattr
lock write setattr append link unlink rename };

That is right at the top of the list.  The (5597) is a link directly to
the line in policy.conf (in another tab).

Doing the same search on the binary policy file will actually expand
httpdcontent into httpd_sys_content_t.

I also could have found it by leaving the Booleans alone and disabling
"Only search for enabled rules".  The information flow analysis
(Analysis tab) requires the Booleans to be set, but they also find the
rule.
