Previously, since response (.rsp) files weren't expanded at the very beginning of clang-scan-deps, we only parsed the command-line as provided in the Clang .cdb file. Unfortunately, when using Unreal Engine, arguments are always generated in a .rsp file (ie. `/path/to/clang-cl.exe @/path/to/filename_args.rsp`). After this patch, `/Fo` can be parsed and added to the final command-line. Without this option, the make targets that are emitted are made up from the input file name alone. We have some cases where the same input in the project generates several output files, so we end up with duplicate make targets in the scan-deps emitted dependency file.
