setup: prepend os.getcwd() to misc/dependencies

This is actually useful because if for example you invoke "easy_install
~/some/path/setup.py", then the CWD will be ~/some/path when the first part of
setup.py is evaluated, but will change to something else later, so the
misc/dependencies will not be found unless the CWD is prepended.  ***END OF
