lib-git-svn.sh: Avoid setting web server variables unnecessarily

If the SVN_HTTPD_PORT variable is not set, then we will not even
attempt to start a web server in the start_httpd function (despite
it's name), so there is no need to determine values for the
SVN_HTTPD_PATH and SVN_HTTPD_MODULE_PATH variables.
