 Looking through and testing
 [https://core.trac.wordpress.org/attachment/ticket/16293/16293.4.diff
 16293.4.diff] again.

 Requirements for deleting a user from the network:
 * Current user can `manage_network_users`
 * Current user has `delete_user` cap
 * User being deleted is not a super admin
 * The email of the user being deleted is not currently set as the network
 admin email

 If these are in order, a user with an ID of 1 can be deleted using bulk
 actions. A user with an ID of 1 cannot be deleted using the ''delete'' row
 action link even though the ''delete'' row action link appears. There are
 no restrictions on a user ID of 2, contrary to the ticket title.

 16293.4.diff does the trick as all the existing checks take care of normal
 concerns when deleting users from the network.

 '''If''' the `manage_network_users` capability is assigned to user ID 1,
 they are no longer a super admin, '''and''' the `delete_user` meta
 capability is mapped to the user—they can delete themselves from the
 network after reassigning content to another user. This is the case with
 any user other than ID 1 as well. The experience is actually not that bad
 if you're expecting it. :)
