gpg: can't connect to the agent: File name too long

Looks like gpg doesn't like long paths, so we should put the temporary gpg database in /tmp instead (and fix the permissions to 700 to silence the other warnings).

I test a branch with above approach [1] and the error of long names is not longer present, but there is still an error on agent sending keys. I was researching and this seems to be a compatibility issue [2][3]. 

After failures on morty (supports python3) gpg was updated to 2.1.15 on workers, after that update this failure is not present anymore on morty, pyron and current master (all with support for python3) but starts failing for krogoth (python2). As this is only happening on krogoth branch and in Ubuntu 16.10 on which is not longer supported at AB. setting this as wontfix.
