    PR29676: Wildcard expansion fix for labels

    PR29676, introduced an bug where function symbols from the symbol

    table were expanded in the function component resulting in wildcards

    not being expanded in labels. This fix, removes the issue by restricting

    the symbol table query to probes which don't need further debuginfo to

    expand.
