trackingtester in ctest does not use correct bdsim binary

[Jochem Snuverink]

ctests for trackingtester uses the local bdsim binary instead the one from PATH:

from pymadx:

        _os.system("bdsim --file="+self.filename+".gmad --ngenerate="+str(self.nparticles)+" --batch --output=root --outfile="+self.filename+" > bdsim.log")

A mechanism should be found such that within ctest the local binary is used

[Jochem Snuverink]

fix issue #92 : add bdsim binary and cmake-found madx binary to tracking tester; replace with .in file
