Subject: gitlab: manifest: Use a cerbero ref with build
X-Git-Tag: 1.19.3~497^2~348
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1e27cc81b167a6f0c8cfb3dcdd65b8d37d8c8ee3;p=platform%2Fupstream%2Fgstreamer.git

gitlab: manifest: Use a cerbero ref with build

For non-cerbero builds, pick a cerbero reference for which a build has
completed. This will reduce the number of cache miss, hence reduce the
number of timeouts and slow build we are facing each time cerbero is
updated.

Fixes #16
