runtime: Switch to using the rust version of virtiofsd (all but power)

So far this has been done for x86_64.  Now that the support for building
and testing has been added for all arches, let's do the second part of
the switch.

We're still not done yet for powerpc, as some a virtifosd crash on the
rust version has been found by the maintainer.

Fixes: #4258, #4260
