perf symbols: Add machine id to modules debug message
Current debug message is: Problems creating module maps, continuing anyway... When running multiple VMs it would be nice to know which machine the message is referring to: $ perf kvm --guest --guestmount=/tmp/guest-mount record -av -- sleep 10 Problems creating module maps for guest 6613, continuing anyway...
