Bug #99905 for CPAN: Create missing site library directories

Some vendors configure site library directories into /usr/local, but they do not provide the directory on their systems because an administrator can have a read-only network-mounted file system there. When running CPAN for the first time, CPAN cannot find the site directories and falls back to local::lib. To restore the user expectations with writable /usr/local, atteched patch tries to create the missing directories before checking for their presence.
