[PATCH] D23606: [LLVM] [cmake] Ensure proper -I along with -include on SunOS, #29013

As described on the bug, the '-include' flag added to C++ flags on SunOS gets propagated to subprojects such as libc++ while they do not have matching include directories enabled. This simple patch adds an -I flag along with the -include to ensure that the compiler is able to find the requested include.
