llvm-rc: Depfiles are written into source tree when llvm-rc is used as RC compiler

In CMake 3.17, when using llvm-rc as the CMAKE_RC_COMPILER, .d depfiles are incorrectly written into the source tree instead of the build tree. This looks to be caused by the following piece of the `CMAKE_RC_COMPILE_OBJECT` rule: `-clang:-MD -clang:-MF -clang:<SOURCE>.d`.
