selftests/vDSO: Add riscv getcpu & gettimeofday test

Browse Source 
Enable vDSO getcpu & gettimeofday test for riscv. But only riscv64
supports __vdso_gettimeofday and riscv32 is under development.

VERSION
{
        LINUX_4.15 {
        global:
                __vdso_rt_sigreturn;
                __vdso_gettimeofday;
                __vdso_clock_gettime;
                __vdso_clock_getres;
                __vdso_getcpu;
                __vdso_flush_icache;
        local: *;
        };
}
