Create an artificial module using a JSON object file when we can't
locate the module and dSYM through dsymForUUID (or however
locate_module_and_debug_symbols is implemented). By parsing the symbols
from the crashlog and making them part of the JSON object file, LLDB can
symbolicate frames it otherwise wouldn't be able to, as there is no
module for it.
For non-interactive crashlogs, that never was a problem because we could
simply show the "pre-symbolicated" frame from the input. For interactive
crashlogs, we need a way to pass the symbol information to LLDB so that
it can symbolicate the frames, which is what motivated the JSON object
file format.

Sometimes, it can happen that a crash report has null images in its list
of used binaries. This manifests like such:
```
0x0 - 0xffffffffffffffff ??? (*) <00000000-0000-0000-0000-000000000000> ???
```
When fetching debug symbols to symbolicate the crashlog stackframe,
having null images causes `dsymForUUID` to hang for few seconds.
This patch addresses that by skipping null images from being load by the
scripted process.

This patch should fix the interactive crashlog test by checking in the
binary as a yaml to regeneate the binary with the addresses and offsets
when running the test.
