pkg: change trace print to debug log

[alxric]

These print messages can turn out to be very noisy as it prints exceptions quite often as some processes (such as libc amongst others) pass function names as integers instead of strings which causes panics further along.

As that seems to be caused by dwarf allowing deduplication of strings into other sections which is not yet supported by parca, change this print to a debug statement instead so that it doesn't clutter the log during normal operations
