Entware-arm install script deleted old installation

[LeeWiu]

I reinstalled entware and I had a big surprise, old entware.arm folder was deleted by the script and I lose all chrooted debian instalation, thanks to God my Media folder wasn't mounted in /debian/mnt I modified the script to rename entware.arm to entware.arm-old+date instead of deleting, and can be deleted manually after :) Please update and commit to asuswrt-merlin too. Thanks

Old folder is deleted in mipsel script version. I do not think arm and mipsel versions should behave differently.
