vmstate static checker: detect section renames

Commit 292b1634 changed the section name of "ICH9 LPC" to "ICH9-LPC",
and that causes the static checker to flag this:

Section "ICH9 LPC" does not exist in dest

This patch introduces a function that checks for section renames and
also a dictionary that maps those renames.

This is a small patch to a script; doesn't break qemu and helps with the
static checker, so it's a very low-risk patch for 2.1.
