[PATCH] Tweak NM-wait-online.service

[Bill Nottingham <notting redhat com>]

Comments? With this, distributions who wanted to could unilaterally enable
this service and yet have it only slow down the boot when something
explicitly is asking for synchronization on network availability.

(I still don't think we would ship Fedora this way, but some other
distribution might.)

    Tweak NM-wait-online.service.
    
    1) Don't require NM, but run after it. This allows this service to be installed without
    bringing up NetworkManager. Add -x so that it exits if NM isn't running.
    
    2) Install as a want of network.target, instead of multi-user.target. This allows us to skip it
    if nothing requires network.target or the legacy $network SysV capability.
