The post-run "target modules list" output orders the OS DLLs (ntdll,
kernel32, ...) by load address, which differs between the in-process
debugger and the lldb-server-on-Windows path. The exact order is not
what this test cares about. The goal is to verify that preloaded
dependent modules are not duplicated once the inferior actually loads
the DLL.
This patch replaces `CHECK-NEXT/CHECK` lines with `CHECK-DAG`, keeping
the trailing `CHECK-NOT` to enforce no duplicate `shlib.dll` entry.
