Harden config protection .htaccess

+ Set "Satisfy All" whenever available, as well on Apache 2.4+. This is required to override possible "Satisfy Any" on parent dir, which otherwise would allow direct access to data, regardless of "Require" directive.
+ Set "Deny from all" as well whenever available, to block access regardless of which access control directive takes priority.
+ Assume Apache 2.2 only, if mod_authz_core and mod_access_compat are both not available, to avoid doubled directives. In this case set "Deny from all" directive only if the providing mod_authz_host module is available. "Satisfy" is a core directive on Apache 2.2.
+ Update Apache version strings. Regarding the used directives/modules, Apache 2.4 and 2.5 behave the same.
+ Add ordering spaces to better reflect the nested directives and to match style of other .htaccess files.

Fixes: #6449 (for the config directory)
