Markus Armbruster 164e7dd73c scripts/cleanup-trace-events: Fix for vcpu property
Commit a44cf524f8 "scripts/cleanup-trace-events: Update for current
practice" limited search to the input file's directory.  That's wrong
for events with the vcpu property, because these can only be defined
in root directory.
