    Fix for downloading uwsgi on centos in lib/apache

    On Centos the lib/apache script in devstack downloads and compiles
    uwsgi package. It uses pip-download to pull uwsgi tar file.
    However, it does not return the full name of downloaded file so
    right now the script looks for filename that starts with prefix
    "uwsgi".
    This method is case sensitive so after downloading file with name
    uWSGI-2.0.19.tar.gz the script was unable to locate this file.

    This change downloads the file to an empty directory and expect
    it to be the only file there so there is no name vulnerability.
