apache2_module: updated cgi action conditions (#10423)
* apache2_module: updated cgi action conditions
Only the activation of the cgi module in threaded mode should be a
restriction due to apache2 limitations, not the deactivation.
Especially when the cgi module isn't enabled yet at all. Fixes#9140
* bug(fix): apache2_module fails to disable cgi module
* Update changelog fragment.
