[llvm-readobj] - Don't crash when dumping invalid dynamic relocation.

Currently when we dump dynamic relocation with use of
DT_RELA/DT_RELASZ/DT_RELAENT tags, we crash when a symbol index
is larger than the number of dynamic symbols or
when there is no dynamic symbol table.

This patch adds test cases and fixes the issues.
