run-tests: ensure install directories exist

As part of the transition to setuptools, it was discovered that
setuptools doesn't create install directories for you where distutils
apparently did. This was causing run-tests.py to fail when creating the
temporary hg install.

We work around this problem by creating the install directories before
running setup.py.
