Cannot build from local source files using Dockerfile

[PierreRustOrange]

The docker file in the repository pulls the sources it compiles directly from two github repositories:

• https://github.com/gfieni/libpfm4.git (msr-pmu-old branch)
• https://github.com/powerapi-ng/hwpc-sensor.git

This means that it cannot be used to build the sensor in development with locally modified sources files. That would be less of a problem it the sensor could be easily build using the provided makefile but no matter the dependencies I install I never managed to build outside docker on my ubuntu 20.04 box.
