Warnings during build time tests about missing components

[Mateus Rodrigues de Morais]

This task was recommended as a TODO during the nvme-stas MIR review:

Original comment:

  Build time tests complain about missing components skipping tests
  ../test/meson.build:79: WARNING: Dbus daemon is not running
  ../test/meson.build:85: WARNING: Avahi daemon is not running
  ../test/meson.build:111: WARNING: Skip Avahi Test due to missing dependencies
  ../test/meson.build:151: WARNING: Skiping some of the tests because "vermin" is missing.
  Would it pollute/break the build if you'd build-depend (with !nocheck)?
  Because if that could work it would be an easy win for QA.
  If you are concerned of the build env, then consider re-run this test in an
  autopkgtest stage?
