[PATCH] Doc/SubmitChecklist: add rule #1

[Randy Dunlap <randy.dunlap@oracle.com>]

From: Randy Dunlap <randy.dunlap@oracle.com>

Add header file requirements.
Complements of Stephen Rothwell.

Stephen calls this Rule #1, so I put it there, but I
didn't want to demote any of the others in the list,
so I made one of them number 2b.
