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

[krasimirgg]

No functional changes intended.

This updates the test case to use llvm-nm as an alternative to #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 #94023.

This message looks wrong: after squashing, the correct commit of this PR should be c1ed82f. Not sure if I did something wrong?

Path to llvm-nm must have had mix of forward and backward slashes.

I'll try escaping this differently. Not sure how to re-try the i686-mingw-1 checks.

[nikic]

Seems to use the same spelling as other LLVM tools in tests now, so let's hope that works...
