[analyzer] Remove breaking RUN line in the test case

This is a followup for D118690.
I'm removing the offending RUN line, to resolve the build breakage:

https://lab.llvm.org/buildbot/#/builders/91/builds/3975/steps/8/logs/stdio

Exit Code: 1
Command Output (stderr):
--
/scratch/buildbot/bothome/clang-ve-ninja/llvm-project/clang/test/Analysis/analyze-function-guide.cpp:58:22:
error: CHECK-EMPTY2-NOT: excluded string found in input
