Daemon will not start in Debian

Attempting to use the module in Debian yields the following:

    => default: Debug: Executing 'supervisorctl reread'
    ==> default: Notice: /Stage[main]/Supervisord::Reload/Exec[supervisorctl_reread]/returns: error: <class 'socket.error'>, [Errno 2] No such file or directory: file: /usr/lib/python2.7/socket.py line: 224
    ==> default: Error: /Stage[main]/Supervisord::Reload/Exec[supervisorctl_reread]: Failed to call refresh: supervisorctl reread returned 2 instead of one of [0]
    ==> default: Error: /Stage[main]/Supervisord::Reload/Exec[supervisorctl_reread]: supervisorctl reread returned 2 instead of one of [0]

The issue was the init.d file:

    DAEMON=<%= @executable %>
    NAME=supervisord
    DESC=supervisor

    test -x $DAEMON || exit 0

`DAEMON` was simply `supervisord` which wasn't being found. Then the `test -x` wouldn't find the executable and would silently exit.

This is now resolved by choosing the correct install path in Debian/RHEL OS's. The test was added into the RHEL init.d file, as well as using a `$CTL` variable for the `supervisorctl` executable.

This also undoes b702b82c3122d99b2917aa212e7a8cd9aa40c557 because it should fail when the executable is not properly started!
