T6674: Add build-scrips for packages without Jenkins

Add build scripts for .deb packages without Jenkins.
To exclude Jenkins we need some place where we can put new builds-scripts
to run in parallel (old/new) during meantime
We will deprecate old Jenkins package builds in the future.

+Subject: [PATCH] VyOS: add inotify support for stackable filesystems
+ (overlayfs)
+
+As it stands at the moment, overlayfs doesn't have full support for
+inotify, and as such anything that relies on inotify currently has
+issues.  The simplest method of demonstrating this is to tail a file
+(so tail -f /var/log/messages) and see that it doesn't follow changes
+in that file.  This has been reported in a number of places, including
+Bug #882147 in Ubuntu.  This patch is based on the version proposed by
+Li Jianguo in response to this bug, adding support for inotify in
+stackable filesystems.
+
+This commit provides a complete fix for the workaround implemented
+for bug #303, and will allow that commit to be reverted.
+
+Bug #425 http://bugzilla.vyos.net/show_bug.cgi?id=425
+
+(cherry picked from commit a93f1128bc83b5a6628da242e71c18ef05e81ea2)
