The syscall livepatch selftest resolves and patches a syscall wrapper symbol. To use that test for RISC-V livepatch validation, add the RISC-V FN_PREFIX definition for ARCH_HAS_SYSCALL_WRAPPER. Without this macro, the syscall livepatch selftest cannot resolve the RISC-V target symbol, and the syscall-related livepatch test fails on RISC-V.
