[llvm-readelf] - Do not error out when dumping symbols.
When the --symbols option/--dyn-symbols is given we might report an error and exit when something goes not right. E.g. when the SHT_SYMTAB section is broken. Though we could report a warning and try to continue dumping instead in many cases. This patch removes `unwrapOrErr` calls from the code involved in the flow described.
