Jonas Devlieghere 17e226f71e [lldb] Fix crash when passing a folder in as the executable (#175181) ...

This is another instance where we weren't checking that the result of
FileSystem::CreateDataBuffer and unconditionally accessing it, similar
to the bug in SourceManager last week. In this particular case,
ObjectFile was assuming that we can read the contents non-zero, which
isn't true for directory nodes.

Jim figured this one out yesterday. I'm just putting up the patch and
adding a test.
