subversion: fix CVE-2015-3184

mod_authz_svn in Apache Subversion 1.7.x before 1.7.21 and 1.8.x before
1.8.14, when using Apache httpd 2.4.x, does not properly restrict
anonymous access, which allows remote anonymous users to read hidden
files via the path name.

Patch is from:
http://subversion.apache.org/security/CVE-2015-3184-advisory.txt
