Removes read, write and execute access for others for all users who have home
folders under folder /home by running for example "chmod o-rwx /home/user"
 during package installation or upgrade. This will be done only once per folder
 in folder /home so users who wish to relax file permissions are free to do so.
 This is to protect previously created files in user home folder which were
 previously created with lax file permissions prior installation of this
 package.
