[pkg-gnupg-maint] Bug#853905: Ships incorrect /usr/lib/systemd/user/sockets.target.wants files, makes disabling impossible

[Yuri D'Elia]

Package: gnupg-agent
Version: 2.1.18-3
Severity: normal

According to upstream, it's incorrect to ship user/sockets.target.wants/* files
directly, as those cannot be disabled by the administrator.

Quote:

  ... should instead ship this with an [install] section and enable it at
  package install time with "systemctl preset --global gpg-agent.socket" ...
  that you way can "systemctl disable --global gpg-agent.socket" whenever you
  like.
