docs/tools/virtiofsd.rst: Do not hard-code the QEMU binary name

In downstream, we want to use a different name for the QEMU binary,
and some people might also use the docs for non-x86 binaries, that's
why we already created the |qemu_system| placeholder in the past.
Use it now in the virtiofsd doc, too.
