gitlab: Update software to gitlab 8.7

Update GitLab software to

    - gitlab-ce 8.7.9 + NXD patches

    - gitlab-shell to 2.7.2 + 1 patch to remove unneeded hooks.old in *.git

    - gitlab-workhorse stays at 0.7.1 + NXD patches because gitlab-ce 8.7.x
      sticks to this version (i.e. no workhorse upgrade for gitlab 8.6 -> 8.7)

This only updates software and begins SR update to 8.7 - for now gitlab
instance becomes non-working -- we'll pull in configuration files
updates and fixups in the following patches.
