switch to default debian8

[anantshri]

Current build is only used coz i needed a specific android user with tamer password but i suppose all that can also be configured via using default box and then performing some high level action and then switching to that specific user for all purposes.

That way we will not be forcing people to download our box specifically.

for tamer5 we are keeping as is created a new debian 11 custom box.
