Fixed some problems with fresh checkouts of projects that don't include
``.egg-info/PKG-INFO`` under revision control and put the project's source
code directly in the project directory. If such a package had any
requirements that get processed before the ``egg_info`` command can be run,
the setup scripts would fail with a "Missing 'Version:' header and/or
PKG-INFO file" error, because the egg runtime interpreted the unbuilt
metadata in a directory on ``sys.path`` (i.e. the current directory) as
being a corrupted egg. Setuptools now monkeypatches the distribution
metadata cache to pretend that the egg has valid version information, until
it has a chance to make it actually be so (via the ``egg_info`` command).
