[llvm-readobj/elf] - Don't crash when the size of s dynamic symbol table, inferred from the hash table, is broken.
Currently we might derive the dynamic symbol table size from the DT_HASH hash table (using its `nchain` field).
It is possible to crash dumpers with a broken relocation that refers to a symbol with an index
that is too large. To trigger it, the inferred size of the dynamic symbol table should go past the end of the object.
This patch adds a size validation + warning.
