Revert "pdbtool: If a test message has no program attribute, warn when verbose"

This reverts commit d5a01d0e789d1792ab385ab194bf47a7fe1dd639.
pdbtool test: examples lacking $PROGRAM or $MESSAGE value are printed too

Previously examples that lack $PROGRAM or $MESSAGE value were not printed
to the test log at all. With this patch, the fact that these are ignored
is printed to stdout.
