    Update pre-install hooks to fail on error

    The pre-install operations may fail, yet that failure is not
    elevated to the user. This masks the failure and makes early
    package install issues difficult to troubleshoot.

    If the basic pre-install script fails, the charm should not
    proceed to later hooks as the requirements may not be met.

    Hashbangs for bash should specify -e (errexit) on all of the
    pre-install bash scripts.
