Increase verifiability of security checks

This patch introduces a series of patches that will provide tools which
will succeed current security check scripts. Its two main reasons are:

* increasing tools verifiability by providing internal tests,
* improving "expected failure" support by suppressing carefully selected
  set of special cases.

Each tool will use following directory structure (generated with
"tree -a --charset=ascii" command):

.
`-- check_module
    |-- Dockerfile
    |-- .dockerignore
    |-- .gitignore
    |-- go.mod
    |-- main.go
    |-- Makefile
    |-- README
    |-- README.rst -> README
    `-- submodule
        |-- submodule.go
        `-- submodule_test.go

This will allow using Go Modules mechanism within its limitations [1]
for "non-go-get-able modules" [2][3][4] - also in case of separating
code into several modules used by multiple "check modules", e.g.

.
|-- common
|   |-- common.go
|   |-- common_test.go
|   `-- go.mod
`-- check_module
    |-- go.mod
    `-- ...

It would require migration from separate Dockerfiles to a single one
(multi-stage), though.

Provided Makefiles are intended to simplify local development
(Docker-less building) and container images preparation. READMEs clarify
utility requirements and usage - file without extension is for VCS
reference, symlink for proper syntax rendering.
