Bug 618858 - move start-ds-admin env file into main admin server
    config path

    Description by Ulf Weltman (ulf.weltman@hp.com):
    To improve feng-shui on HP-UX we modify the layout by moving
    start-ds-admin's env file dirsrv-admin from
    /etc/opt/dirsrv-admin/config to /etc/opt/dirsrv/admin-serv.
    (On HP-UX we keep files in /opt/dirsrv, /var/opt/dirsrv and
    /etc/opt/dirsrv.  That additional /etc/opt/dirsrv-admin path
    was awkward since it just contained the single env file.)
    
    I had to move the assignment of the instancename variable up
    in the file so it's available when the initconfigdir is set.
