www/freenginx-devel: update from 1.29.2 to 1.29.3

<ChangeLog>

*) Feature: loading of certificates and secret keys from hardware tokens
   with OpenSSL STORE API.

*) Change: loading of external character entities declared in the
   internal DTD subset is now disabled by default in the
   ngx_http_xslt_filter_module; loading can be enabled with the
   "xml_external_entities" directive.

*) Bugfix: the ngx_http_xslt_filter_module might try loading of external
   character entities over the network, which might cause blocking of
   the worker process for a significant time.

*) Bugfix: the "working_directory", "google_perftools_profiles",
   "geoip_country", "geoip_city", "geoip_org", and "xml_entities"
   directives incorrectly handled relative paths.
