VSS to DDS-IDL exporter inclusion in make file

I triggered the build. (For first time contributors builds must be triggered manually by someone with write/admin rights). The build fails - the vss-tools submodule needs to be updated so that the Python file is available for the build. That could however possibly be synched with the GraphQL change as they also will need to change the Makefile.

Suggestion: @danielwilms - if you first update VSS Makefile and submodule reference to handle the changes in COVESA/vss-tools#166, then @zam1kor does not need to update submodule reference. I.e. first integrate the GraphQL changes, then the DDSIDL changes

./vss-tools/vspec2ddsidl.py -I ./spec ./spec/VehicleSignalSpecification.vspec vss_rel_$(cat VERSION).idl	
/bin/sh: 1: ./vss-tools/vspec2ddsidl.py: not found
make: *** [Makefile:40: ddsidl] Error 127
Error: Process completed with exit code 2.

@erikbosch, will do!

Trivial PR, so I consider that no discussion on the weekly meetings is needed. Build now passes. Will merge it.
