[BUG] inconsistent information in likwid-genTopoCfg

[jdomke]

Describe the bug
Running likwid-genTopoCfg twice results in missing information (architecture) and incorrect information (featureFlags), see below. The ERROR and 'Cannot read' messages shouldn't be shown to not confuse a user who never ran the command before and has no idea about the likwid internals, but that is just a side note.

domke@a64fx ~/ $ likwid-genTopoCfg 
ERROR - [/home/domke/likwid/src/topology.c:readTopologyFile:288] No such file or directory.
Cannot read topology information from file /home/domke/likwid/etc/likwid_topo.cfg
