[Bug] Writing to exfat drive on linux

[paulhayes]

What / Why

I'm writing to an external exfat formatted drive on linux. This is a root mounted drive with no permissions system, so everyfile is owned by root, with full rw access to all users. So I have read, write access to the file.

write-file-atomic is trying to set the ownership of the file.
chown: changing ownership of '/media/sandisk/config.json': Operation not permitted

I know that you advice to pass false to the permission option, however this is a 2nd level dependancy, so I'm not actually using this library directly. I'm using
json-future, which has a dependancy for write-json-file, which is using write-file-atomic.

I think if write-file-atomic is just going to set the uid to the existing user, it could catch this error and squash it, as chown failing has no impact.
