subrepo: setting LC_MESSAGES only works if LC_ALL is empty or unset

For example LC_ALL=de_DE.utf-8 would cause the version check to fail,
because "svn, Version 1.6.12 (r955767)" with a capital "V" will be printed.
Using "svn --version --quiet" would only print the version number, but then
matching other messages, e.g. "Committed revision" would fail.
