[Bug 1827759] [NEW] Doesn't work properly with umask 027

[kolya]

Public bug reported:

Usecase:

* Have a non-admin user with umask 027
* That non-admin user does 'sudo apt ...' that triggers rebuild of /var/lib/command-not-found/commands.db

The result is that /var/lib/command-not-found/commands.db is no longer
readable by any non-root user because user's umask gets inherited and
used.

Expected: regardless of what umask non-root has command-not-found
database should be readable by everybody.
