Update git-svn manpage to remove the implication that SVN::* is optional.

Now that git-svn requires the SVN::* Perl library, the manpage doesn't need
to describe what happens when you don't have it.

 BUGS
 ----
 
-If you are not using the SVN::* Perl libraries and somebody commits a
-conflicting changeset to SVN at a bad moment (right before you commit)
-causing a conflict and your commit to fail, your svn working tree
-($GIT_DIR/git-svn/tree) may be dirtied.  The easiest thing to do is
-probably just to rm -rf $GIT_DIR/git-svn/tree and run 'rebuild'.   You
-can avoid this problem entirely by using 'dcommit'.
-
 We ignore all SVN properties except svn:executable.  Too difficult to
 map them since we rely heavily on git write-tree being _exactly_ the
 same on both the SVN and git working trees and I prefer not to clutter
