Improve performance of the "fix permissions" step in ncp-update-nc

[powerflo]

The "fix permissions" step is really slow when the nextcloud folder contains a lot of data. In a docker setup the data directory is in nextcloud/data so the folder can be really big. Even on my small test setup the "fix permissions" step took more than 20 minutes. Using "chmod -R ..." reduces the time to around 20 seconds.

This should really be merged, the fix permissions step took more than 30 minutes on my setup.
