Bug#585524: also same problem - chmod fixes

[Mark Hedges <hedges@scriptdolphin.com>]

Or should it be:

 bdir=/usr/lib/cups/backend
 chown -R root:lp $bdir
 chmod 2750 $bdir
 chmod 0750 $bdir/*
 chown root:lp /usr/bin/smbspool
 chmod 0750    /usr/bin/smbspool

Other apparent problem, looks like /usr/bin/smbspool should
be an absolute path link and root:lp 0750.
