qemu: Remove --posix-acl and add --no-announce-submounts to virtiofsd

--posix-acl causes an error from virtiofsd saying the client doesn't
support this feature. We also get a warning about announcing submounts
not being supported so let's make sure we disable both features to
avoid these warnings/errors.
