  [ObjectYAML] - An attempt to fix BB after commit of D95140.

D95140 introduced `static constexpr StringRef TypeStr = "SectionHeaderTable";` member
of `SectionHeaderTable` with in-class initialized. BB reports the link error:

/usr/bin/ld: lib/libLLVMObjectYAML.a(ELFYAML.cpp.o): in function

This patch adds a definition to cpp file, I guess it should fix the issue.
