[PATCH] svn_load_dirs.pl: fix rm temporary folder

Hello,

I am contacting you to propose 2 patch files for the script
svn_load_dirs.pl located at the URL below:
http://svn.apache.org/repos/asf/subversion/trunk/contrib/client-side/svn_load_dirs/svn_load_dirs.pl.in

This email discusses the first patch, which avoids failing to delete
the temporary folder with an error like this one:
"cannot remove path when cwd is
/tmp/svn_load_dirs_ATrGGCJoWv/my_import_wc for
/tmp/svn_load_dirs_ATrGGCJoWv"

The error has also been reported at the following link:
http://www.wandisco.com/svnforum/threads/40434-Import-snapshot-folders-requesting-step-by-step-guide-for-using-svn_load_dirs-pl?p=116340&viewfull=1#post116340

I propose a really simple patch, as pasted below (I also send it
attached if you prefer).

Best regards,
Geoffrey
