package_manager/deb: give out useful reason about an unmatched package

Browse Source 
Give out useful information when a package could not be matched.

Before the change:

  E: Package 'catch2' has no installation candidate

With this patch:

  E: Package 'catch2' has no installation candidate
  catch2 is a recipe. Its generated packages are: ['catch2-src', 'catch2-dbg', 'catch2-staticdev', 'catch2-dev', 'catch2-doc']
  Either specify a generated package or set ALLOW_EMPTY:${PN} = "1" in catch2 recipe
