Nick Craig-Wood 5a941cdcdc local: fix preallocate warning on Linux with ZFS
Under Linux, rclone attempts to preallocate files for efficiency.

Before this change, pre-allocation would fail on ZFS with the error

    Failed to pre-allocate: operation not supported

After this change rclone tries a different flag combination for ZFS
then disables pre-allocate if that doesn't work.

Fixes #3066
