Windows vagrant setup is missing c++ compiler

[evenlund]

I get an error that the c++ cant be found when running "docker-compose up prepare" for the windows setup. I have made this work by adding the "build-essential" apt package in the Dockerfile.

There still seems to be an issue that rosdep cannot be found at the end of the running (bash: rosdep: command not found
rosserial_stm32_prepare_1 exited with code 127).
