gitignore: use only one .gitignore file, in the top-level directory

* doc/.gitignore, doc/amhello/.gitignore, lib/Automake/.gitignore,
lib/Automake/tests/.gitignore, tests/.gitignore: Deleted, their
contents merged into ...
* .gitignore: ... this top-level file.  Since we are at it, improve
it by anchoring files where it makes sense.
