Make sure that when a .socket unit is installed without its matching
.service we don't end up activating a legacy SysV/LSB service with the
same name. SysV/LSB style services do not support passing sockets and we
don't want to extend SysV/LSB to ensure we don't break compatibility
with other systems.
