elf: handle missing dependencies not found on system
Metadata
Current evaluation
Merged PR #2746 via ed3f32aa3: ELF scanning now retains unresolved libraries, falls back to sonames, parses ldd output reliably, and tests missing-library cases.
Resolution: closed resolved
Reason: PR #2746 was approved and merged as commit ed3f32aa3. It preserves unresolved ELF dependencies, uses the soname when ldd reports a missing or invalid path, and adds missing-library test coverage.

Issue body
I believe that prior testing involved ldd picking up the
host-installed binaries to properly catch which libs are missing.
Handle the case where ldd may return "not found" or some other
invalid resolution. In those cases, initialize soname_path to soname.
- Update load_dependencies so that it does not filter out libraries
that are not found. If done, the returned set isn't very useful
for determining missing dependencies (unless they managed to get
found on host, which is why it has worked thus far).
- Refactor ldd into its own method and update it to parse ldd
output more reliably.
- Add unit test coverage for missing libraries in ldd output.
