Fix the svn version check issue, append '--quiet' to get svn version string.

In some enviroments (eg, OSX zh_CN), use 'svn --version' and splitting string
may get error version string. Use 'svn --version --quiet' to do stable svn
version check, which directly returns version string such as '1.7.0'.
