[lldb/test] Relax NSBundle formatter test for Darwin embedded platforms (#193659)

Some Foundation APIs have been migrated from Objective-C to Swift while
maintaining backward compatibility. For instance, that can cause
`NSBundle` created via `initWithURL:` to format without the `@"..."`
prefix.

Match the path string without requiring the @ prefix so the test passes
with both the ObjC and Swift implementations
