[Pkg-salt-team] Bug#930178: salt-master: install fails if salt-minion was installed first

[Scott Coil]

Package: salt-master
Version: 2018.3.4+dfsg1-6
Severity: normal

Dear Maintainer,

   * What led up to the situation?
         apt-get -y install salt-minion
         apt-get -y install salt-master
   * What was the outcome of this action?
         salt-master postinst did not exit with success
         /var/lib/salt and /var/run/salt are not writable by the salt user
   * What outcome did you expect instead?
         successful install of salt-master
