Subject: Prevent shutdown while running dpkg

As long as we are running dpkg, keep an inhibitor that
blocks us from shutting down.

LP: #1820886

(cherry picked from commit 96aef11a5cf400377a52f7e93e70944b17e249d1)
(cherry picked from commit 8ea79afcadead5a5b7d94bf8623cb833859f6d80)
(cherry picked from commit c5b8a857f2535fe284426cefda2fbd1bbb3d5808)

Also fixup prepare-release for CI to handle [linux-any] build-dep,
and do the whole autoconf / makefile stuff.
