feat(checker): libebml checker

[peb-peb]

CVES: https://www.cvedetails.com/product/33126/Matroska-Libebml.html?vendor_id=7864

In redhat based distros, the potential version patterns is libebml-1.4.2, but this is not found in debian distros.
But, a multiline regex:

1.4.2
Unknown
EBMLVoid

was mostly constant among various distros.

Since, we have recently added multiline support for checkers. So, this could be a good first issue for new contributors. :)
The task for new contributors would be to:

1. find this new pattern in the binary executable files (you could download packages from pkgs.org)
2. compare them across various distros and versions
3. create the checker using the multiline regex support
