[Object] Always initialized StartOfFile in Archive::Child::Child constructor.

Fixes uninitialized memory access revealed by https://reviews.llvm.org/D146534.

In empty archives, we use Child(nullptr,nullptr,nullptr) in Archive constructor in setFirstRegular. This copies unitialized StartOfFile to FirstRegularStartOfFile, which child_begin may use later.
