riscv: efi: Generate Microsoft PE format compliant images
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.
