[PATCH v2 09/11] KVM: riscv: selftests: Make check_supported arch specific

check_supported() was used to verify whether a feature/extension was
supported in a guest in the get-reg-list test. Currently this info
can be retrieved through the KVM_CAP_ARM_* API in aarch64, but in
riscv, this info was only exposed through the KVM_GET_ONE_REG on
KVM_REG_RISCV_ISA_EXT pseudo registers.
