In my case, for non-scripted process of coredump, I see the module information even when symbol is not found and I see a placeholder object being created for the module. For scripted process, it shows only the main module due to the limitation I pointed in this PR

Target 1 is child elf-core process target. Target 2 is scripted process target

1. **Current State (without my change)**

Target list
```
Current targets:
  target #0: <none> ( platform=host )
  target #1: [vdso] ( arch=aarch64-*-linux, platform=remote-android, pid=1234, state=stopped )
* target #2: /path/to/coredump ( arch=aarch64-*-*, platform=remote-android, pid=3456, state=stopped )
```

2. Sample Image List of child elf-core target. Note the `*` at the end, which indicates placeholder object
```
[0]  0x1234455 [vdso]   /path/to/a.out
[1] 0x1234566  /path/to/libc.so(*)
[2]     ...
```

3. Sample Image list of scripted process target. Only one module is shown

```
[0]  0x1234445 [vdso]   /path/to/a.out
```

**With my PR to ignore load module errors:**

1. Sample image list of scripted process target. All modules are shown, for the ones whose symbols are not found, place holder objects are created similar to non-scripted process targets


```
[0]  0x1234455 [vdso]   /path/to/a.out
[1]  0x1234566  /path/to/libc.so(*)
[2]  0x1245666 /path/to/libb.so
[3]  ...
```
