  This new entrypoint (kickstartfakedisplay.sh) launch Xvfb and pass every parameters to the default entrypoint.sh
• ghdl (VHDL simulator) is added (compiled from github sources) to be able to run vhdl test bench coverage
• yosys (open source synthetizer) is added (compiled from github sources) to be able to run new vhdl rules.
• ghdl plugin for yosys is added (compiled from github sources) to include VHDL support to yosys.
  As soon as tests are converted to pytests, tests will be added to check vhdl feature.
