[flang] Change README to refer to LLVM_BUILD_DIR. (flang-compiler/f18…

…#1033) * Change README to refer to LLVM_BUILD_DIR. LLVM_INSTALL_TOOLS doesn't to install llvm-lit. However pointing to the cmake file in the build directory works fine, and lit and FileCheck will be picked up correctly this way.
