[type/__sshd_config] Produce error if invalid config file is generated

Browse source 
Previously, cdist would silently swallow the error (no invalid config file was
generated).

Reason: `set -e` does not exit if a command in a sub-command group fails,
it merely returns with a non-zero exit status.

e.g. the following snippet does not abort the script if sshd -t returns with a
non-zero exit status:

    set -e
    cmp -s old new || {
        # check config file and update it
        sshd -t -f new \
        && cat new >old
    }

or compressed:

    set -e
    false || { false && true; }
    echo $?
    # prints 1
