[Q][PATCH 1/1] UBUNTU: [Packaging] Don't generate list of source files

[Juerg Haefliger]

BugLink: https://bugs.launchpad.net/bugs/2104911

Generating the list of source files used for the build takes a very long
time on some architecures. Up to 30 mins. Lets not do that. We have all
that information in the debug packages and can collect it from there after
the build.
