[DRE-maint] Bug#1004195: bundler no longer recognizes libraries installed in vendor_ruby (not using gem-install layout) for --local option

[Pirate Praveen]

Package: ruby-bundler
Version: 2.3.5-1
Severity: important

Example package is gitaly. The same build passed when using an older 
bundler (2.2.x). One option is just to switch all packages with old 
layout to use the gem-install layout.

# Test if ruby dependencies are satisfied
TMPDIR=$(mktemp -d); cp ruby/Gemfile $TMPDIR; cd $TMPDIR;\
        RAILS_ENV=development bundle install --local || exit 1;\
        rm $TMPDIR/Gemfile* $TMPDIR/.bundle/config;\
        rmdir $TMPDIR/config; rmdir $TMPDIR
