[PATCH] x86: reserve a boot-loader ID number for Xen

Claim an ID number for Xen in the LOADER_TYPE field.

Also, keep the table in zero-page.txt consistent with boot.txt.

[hpa says: 6 was skipped because I couldn't rule out that it hadn't been
 unofficially used.  It seemed easier to skip it for now.]
