[PATCH bpf-next v3 2/4] selftests/bpf: Enable gotox tests for riscv64

[Chen Pei]

The riscv64 JIT now supports the gotox instruction and jump tables, so
run the tests in verifier_gotox.c on riscv64 too, mirroring what was done
for arm64 and powerpc.

The guard is 64-bit only because the RV32 JIT does not implement gotox.
