efi_loader: 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 U-Boot is generating *.efi images (eg: helloworld.efi) in
which these two members are not zero.
This updates the build rules to tell linker to remove the symbol
table completely so that we can generate compliant *.efi images.
