Hey,

When we introduced "nosymfollow" we didn't add support for it to the new
mount api. Fix that so users making use of the new mount api can
specifiy it in fsmount() and mount_setattr().

This also adds tests.
This is obviously v5.14 material without the need to rush. This can be
found at:

https://git.kernel.org/brauner/h/fs.mount_setattr.nosymfollow

Thanks!
Christian
