Bug#987156: mod_ssl depends on mod_setenvif while it does not

[MichaIng <micha@dietpi.com>]

Package: apache2
Version: 2.4.46-4

When enabling mod_ssl via "a2enmod ssl" while mod_setenvif is disabled, 
it becomes apparent that mod_ssl depends on mod_setenvif. I checked the 
configuration file /etc/apache2/mods-available/ssl.conf, but it actually 
does not use any mod_setenvif directive. I disabled mod_setenvif 
effectively by emptying setenvif.load and setenvif.conf manually on two 
servers, and none shows any issues for months of 24/7 use.

Hence I believe that this module dependency might come from some 
previous use of setenvif directives in the default mod_ssl config, which 
have been removed meanwhile, rendering this dependency as obsolete.

I'm not sure how those dependencies are defined and whether hence it is 
an upstream issue or a distro package issue. In case I'll report it 
upstream as well.

Best regards,

Micha
