[Bug 1870811] Re: compile auto test failure, and root-unittest failure, is extremely noisy

[Dan Streetman]

** Description changed:

  [impact]
  
  failure in the compile-time tests (also run from the root-unittest
  autopkgtest) prints out the entire meson testlog.txt, which shows the
  output of all tests, including passed ones, not just the failed test
  output.  This makes it extremely difficult to find the output of the
  failed test(s) and creates a massive log to download.
  
  [test case]
  
  see any failed build or failed root-unittest, e.g.
- https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-eoan/eoan/ppc64el/s/systemd/20200331_010822_1c88e@/log.gz
+ https://launchpadlibrarian.net/471257226/buildlog_ubuntu-eoan-amd64.systemd_245.218-g69d06b7acf+19.10.20200328163536_BUILDING.txt.gz
  
  [regression potential]
  
  any regression would likely occur during test failure, likely resulting
  in lack of details of the test failure; or, a regression caused by the
  additional meson parameter could cause build failure.
  
  [scope]
  
  Xenial does not use meson, so can not be adjusted.  This is needed in
  Bionic and later.
