Package cve-manager: Information

- Package releases are taken into account when excluding issues;
- The "cve-issues" module can process manually specified package
  versions/releases (the "cve-monitor-check-update" module is no longer needed
  and has been removed).

- Fixed issues detection for the kernel packages.

- Backslashes, which may be part of the names of vendors and products imported
  from NVD lists, are ignored (they are used to escape special symbols in the
  names and at the same time they complicate the processing or require the use
  of escape symbols in the "cve-manager-inner-knowledge" lists).
