Move Flare Capa and Floss from binary download to pip installation

[mlodic]

Right now those two tools are installed from the malware_tools_analzyers Docker Integration by downloading the binary.
This solution is not optimal because it makes difficult to track updates and the downloaded binary is made for a single arch.
We should try to rewrite the analyzers to leverage the officialy supported python libraries.
See: https://pypi.org/project/flare-capa/ and https://pypi.org/project/flare-floss/

It can be more complicated than expected because these libraries were not built to provide easy classes to import and use
