Upstream QEMU commit: eed968607d656a218712df47a5e0432c21fd6994
hw/9pfs: Remove O_NOATIME flag from 9pfs open() calls in readonly mode

When a 9p filesystem is exported with the readonly flag, QEMU adds the
O_NOATIME flag to all accesses. This causes all reads to fail when qemu
is run as non-root and the runas user doesn't own the files being
accessed. The patch is a one-liner; please add it to the distribution
patches.
