[llvm] Fix build of JITLoaderVTune if ITTAPI_SOURCE_DIR is specified (PR #106924)

[via llvm-commits]

https://github.com/Zentrik created https://github.com/llvm/llvm-project/pull/106924

https://github.com/llvm/llvm-project/blob/357bd61744bb8cc2b9b07447294fa977e5758550/llvm/lib/ExecutionEngine/IntelJITProfiling/CMakeLists.txt allows specifying the source directory of ittapi. This change allows configuring the source directory of ittapi here as well.

Subject: [PATCH 1/2] Use correct ittapi source directory

ITTAPI_SOURCE_DIR is what IntelJITProfiling uses, so I presume this is what should be used here. This fixes building for me as I set `ITTAPI_SOURCE_DIR`.
