svn-support: Disable all mako default filters. #4244

Mako default filter may change the value in a way that breaks the apache configuration.
E.g. when applying HTML escaping.

 # Auto generated configuration for use with the Apache mod_dav_svn module.
 #
 # WARNING: Make sure your Apache instance which runs the mod_dav_svn module is
 #          only accessible by RhodeCode. Otherwise everyone is able to browse
 #          the repositories or run subversion operations (checkout/commit/etc.).
 #
 # The mod_dav_svn module does not support subversion repositories which are
 # organized in subfolders. To support the repository groups of RhodeCode it is
 # required to provide a <Location> block for each group pointing to the
 # repository group sub folder.
 #
 # To ease the configuration RhodeCode auto generates this file whenever a
 # repository group is created/changed/deleted. Auto generation can be configured
 # in the ini file.
 #
 # To include this configuration into your apache config you can use the
 # `Include` directive. See the following example snippet of a virtual host how
 # to include this configuration file.
 #
 #     <VirtualHost *:8080>
 #         ServerAdmin webmaster@localhost
 #         DocumentRoot /var/www/html
 #         ErrorLog ${'${APACHE_LOG_DIR}'}/error.log
 #         CustomLog ${'${APACHE_LOG_DIR}'}/access.log combined
 #         Include /path/to/generated/mod_dav_svn.conf
