This fix is incorrect. Roundcubemail requires mod_php_any, which is only
provided by apache2-mod_php{7,8}, which in turn requires apache2-prefork. It
makes absolutely no sense to also require httpd_daemon or httpd if there is
only one webserver which can provide this dependency, so the correct fix would
be to drop the http_daemon from roundcubemail.

Besides that, if you allow to run on different webservers, they are going to
need different configurations as well and I doubt the roundcubemail package is
completely agostic towards the type of webserver used. It would be much better
if roundcubemail would allow running on different webservers. Put the common
stuff for all webservers would in the roundcube main package and the
configurations for different combinations of webservers and PHP in subpackages.
The main package would then require something each subpackage provides like
(non-exhaustive list, but this should be a hint in the right direction).
