Auto merge of #98573 - krasimirgg:nlmb-llvm-nm, r=nikic

adapt native-link-modifier-bundle test to use llvm-nm

No functional changes intended.

This updates the test case to use `llvm-nm` as an alternative to https://github.com/rust-lang/rust/pull/98424.

This fixes a test failure over at the experimental build of rustc with HEAD LLVM:
https://buildkite.com/llvm-project/rust-llvm-integrate-prototype/builds/11144#01814d0f-a46a-4c19-91cf-41e720edb6f9/684-691.

The issue is that this test uses the system nm, which may not be recent
enough to understand the bitcode produced by rustc when compiled against HEAD LLVM.

Similar to what we did for another test in https://github.com/rust-lang/rust/pull/94023.
