[llvm] [test] Fix expected line number in `TestRunner.py` (PR #73996)

[Stephan T. Lavavej via llvm-commits]

https://github.com/StephanTLavavej created https://github.com/llvm/llvm-project/pull/73996

My #73541 added lines to `llvm/utils/lit/tests/Inputs/testrunner-custom-parsers/test.txt` so what was previously on line 7 is now on line 12.

Before:
https://github.com/llvm/llvm-project/blob/28412d1800e391c5ba8e7607bb15c74b106d581b/llvm/utils/lit/tests/Inputs/testrunner-custom-parsers/test.txt#L7-L8

After:
https://github.com/llvm/llvm-project/blob/6fb7c2d713587a061cd281eda917746750559380/llvm/utils/lit/tests/Inputs/testrunner-custom-parsers/test.txt#L12-L13

This didn't show up in the PR checks, but caused a buildbot failure after merging. Apologies for the build break :scream_cat:
