update_modules.sh does not work on OSX due to lack of timeout command

[Alex Schultz]

With change https://review.openstack.org/#/c/235333/, a timeout command was used to try and prevent librarian-puppet from hanging CI. The problem is that if no timeout command is available the script no longer functions and returns 1. Specifically on OSX this breaks the update_modules.sh and the noop test scripts.

    Fix update_modules.sh to handle missing timeout cmd

    This change fixes the update_modules.sh scrip so that if the 'timeout'
    command is not available it will no longer error. Previously if the
    system did not have a 'timeout' command, the update_modules.sh script
    would fail silently and return 1.
