fix: [Issue #1061] - check for existence before trying to process a file

In certain configurations LLVMConfig.cmake does not exist. If that's the case do_install breaks for the nativesdk-clang recipe.

Eg. set the following:

EXTRA_OECMAKE:append:pn-nativesdk-clang = " -DLLVM_INSTALL_TOOLCHAIN_ONLY=ON"

as suggested here:
