Use distribute instead of setuptools

[Sidnei da Silva]

For some reason setuptools doesn't work anymore on Lucid, making it impossible to 'make build' lazr-js. Since Ubuntu doesn't even ship setuptools, and python-setuptools is actually distribute, it makes sense to move on and use distribute for lazr-js too.

[Sense Egbert Hofstede (sense)]

On Lucid the latest version from trunk still fails when you execute either 'make' or 'make build':

"if test ! -h src-py/lazrjs ; then \
 ln -s ../src-js/lazrjs src-py/lazrjs;\
 fi
python -S bootstrap.py \
  --distribute \
  --setup-source=distribute_setup.py \
  --download-base=download-cache/dist --eggs=eggs
