[compiler-rt] [PGO] Fix `instrprof-api.c` on Windows (PR #77508)

[Qiongsi Wu via llvm-commits]

https://github.com/qiongsiwu created https://github.com/llvm/llvm-project/pull/77508

https://github.com/llvm/llvm-project/pull/76471 introduced a new test but the check line has over-restrictive pattern for a string variable name that causes test failure on Windows (e.g. https://lab.llvm.org/buildbot/#/builders/127/builds/60637/steps/4/logs/stdio). This PR fixes the test.

Subject: [PATCH] Fix test instrprof-api.c on Windows. Use a more general
