perf symbols: Add machine id to modules debug message

Browse Source 
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...
