selftests/vDSO: fix ABI selftest on riscv
Only older versions of the RISC-V GCC toolchain define __riscv__. Check
for __riscv as well, which is used by newer GCC toolchains. Also set
VDSO_32BIT based on __riscv_xlen.
Before (on riscv64):
$ ./vdso_test_abi
[vDSO kselftest] VDSO_VERSION: LINUX_4
Could not find __vdso_gettimeofday
Could not find __vdso_clock_gettime
Could not find __vdso_clock_getres
clock_id: CLOCK_REALTIME [PASS]
Could not find __vdso_clock_gettime
Could not find __vdso_clock_getres
clock_id: CLOCK_BOOTTIME [PASS]
Could not find __vdso_clock_gettime
Could not find __vdso_clock_getres
clock_id: CLOCK_TAI [PASS]
Could not find __vdso_clock_gettime
Could not find __vdso_clock_getres
clock_id: CLOCK_REALTIME_COARSE [PASS]
Could not find __vdso_clock_gettime
Could not find __vdso_clock_getres

Could not find __vdso_clock_gettime
