PR22216, infinite loop in readelf process_symbol_table
This should make readelf bombproof given a fuzzed DT_HASH. Also
removes a bogus check that would have resulted in wrong histograms.
PR 22216
* readelf.c (process_symbol_table): Check that DT_HASH symbol
chains are only visited once, and report an error if not. Display
invalid symbol index if chain is out of range. Use the same logic
when calculating histograms rather than the PR 17531 fix. Delete
bogus check that chained index is less than number of buckets.
