The lighttpd-module-fastcgi package is created (unconditionally) when the
lighttpd recipe is built (you can verify by checking the installable
packages under tmp/deploy/ after building lighttpd).

However, since nothing in the default images has a runtime dependency on
lighttpd-module-fastcgi, that package will only be included in the rootfs
if you manually add it (e.g. by adding to CORE_IMAGE_EXTRA_INSTALL, as you
have done).

ie you need to make the distinction between "is this package being built"
and "is this package being included in the rootfs when the image is built".

I have the lighttpd.conf file set up use mod_fastcgi, and without

It's a similar story with the php-cgi package. It's created
(unconditionally) when the php recipe is built, but will not be installed
in the rootfs unless you add it to your image.

The reason you don't find a direct reference to the string "php-cgi"
anywhere is because the php recipe defines it's list of packages in terms
of the "${PN}" variable. So the php recipe contains references to
"${PN}-cgi" but rather than "php-cgi".
