[lldb/crashlog] Skip null image dsym fetching on interactive mode
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.
