Simon Atanasyan 755b9d9d7d [ELFYAML] Fix handling SHT_NOBITS sections by obj2yaml/yaml2obj tools
SHT_NOBITS sections do not have content in an object file. Now the yaml2obj
tool does not accept `Content` field for such sections, and the obj2yaml
tool does not attempt to read the section content from a file.

Restore r241350 and r241352.
