9pfs: improve portability to older systems
Small requirements on "new" features have percolated to virtio-9p-local.c.
In particular, the utimensat wrapper actually only supports dirfd = AT_FDCWD
and flags = AT_SYMLINK_NOFOLLOW in the fallback code. Remove the arguments
so that virtio-9p-local.c will not use AT_* constants.
At the same time, fail local_ioc_getversion if the ioctl is not supported
by the host.
