The purpose of the userns-restrict BPF-LSM program is to prevent the transient ranges leaking to disk, so let's allow operations outside the transient UID ranges, even if the mount is not allowlisted. This is preparation for the next commits where we'll add support for mapping the current user and the foreign UID range into the user namespaces provisioned by nsresourced. Operations creating files/directories as these UIDs/GIDs should not need the corresponding mount to be allowlisted with nsresourced.
