libvirt/tests/domaincapstest.c
Daniel Henrique Barboza d5ecc2aa77 tests: add QEMU RISC-V "virt" machine in domaincapstest 
'domaincapstest' is currently skipping RISC-V tests. Let's enable it.

The decision of enabling the "virt" machine is based on the idea that
this is the most used QEMU RISC-V machine in the community and it's the
most likely to be widely supported in the long run.
