Per Microsoft PE Format documentation [1], PointerToSymbolTable and NumberOfSymbols should be zero for an image in the COFF file header. Currently the COFF file header is hardcoded on RISC-V and these two members are not zero.
This updates the hardcoded structure to clear these two members, as well as setting the flag IMAGE_FILE_LOCAL_SYMS_STRIPPED so that we can generate compliant *.efi images.
