efi/riscv: libstub: mark when compiling libstub

Commit-Message
We may want to runtime-optimize some core functions (str*, mem*), but not have this leak into libstub and cause build issues. Instead libstub, for the short while it's running, should just use the generic implementation. So, to be able to determine whether functions, that are used both in libstub and the main kernel, are getting compiled as part of libstub or not, add a compile-flag we can check via #ifdef.
