When LTS version of Subversion is set in make.conf (WITH_SUBVERSION_VER)
depending ports will still depend on latest version (devel/subversion)
instead of LTS one (devel/subversion-lts). This will cause dependency
conflicts when packages are distributed with Poudriere, namely pkg(8)
will report them and fail to install.
Make all affected ports properly depend on the right port based on the
value set in WITH_SUBVERSION_VER.
