subrepo/svn: make rev number retrieval compatible with svn 1.5 (issue2968)

ae2664ee0223 introduced "svn info TARGET@REV" to determine if a certain
path exists in the specified revision, but in svn 1.5 the error message
"Not a valid URL" yields exit code 0 so the error is not caught.
Use "svn list TARGET@REV" instead which works with svn 1.5 and is even
faster in some situations.
