ELF: Wrong string table used for symbol names

[jeffman]

When importing an object file: if the section header string table is stored after the symbol string table, then it will be used as the symbol string table as well. The symbol names will then be totally wrong and cause undefined symbol errors.

Somewhere around line 414 in ElfFile.cpp, there should be a check to see if the current section is the section header string table before assigning section to strTab.
