Fix the build of non-kernel code that includes the RISC-V ptrace uapi header, and the RISC-V validate_v_ptrace.c kselftest, by using the _BITUL() macro rather than BIT(). BIT() is not available outside the kernel. Based on patches and comments from Charlie Jenkins, Michael Neuling, and Andreas Schwab.
