Set umask to 022 instead of the default 077 (closes #2551840) When running tests, make sure we generate world-readable files, because: - checking out a hg repo obeys umask - distutils sdist uses hard links from the source tree when preparing its release tree (and thus uses the same permissions) - distutils sdist doesn't force sane file permissions when it creates a tarball - we could work around the above by setting TAR_OPTIONS when calling sdist, but that would only work with python 2.6 because 2.7 uses the tarfile module instead of forking tar This should fix issues like https://www.logilab.org/ticket/115578
