Subject: [PATCH] Adds USERMAP_NOPERM_CHANGE env

Adds a new USERMAP_NOPERM_CHANGE to disable recursive permission change on the home folder of paperless.
On some systems (where the user uses slow storage such as HDD) this operation takes quite a while.
The default behavior is to enable the recursive permission change.
The default value is false. If this is true, the container avoids recursive permission change as documented here: https://github.com/paperless-ngx/paperless-ngx/discussions/5086 and in the man page.
