PR29846, segmentation fault in objdump.c compare_symbols

Fixes a fuzzed object file problem where plt relocs were manipulated
in such a way that two synthetic symbols were generated at the same
plt location.  Won't occur in real object files.

PR 29846
PR 20337
* objdump.c (compare_symbols): Test symbol flags to exclude
section and synthetic symbols before attempting to check flavour.
