Fix aml-s9xx-box bsp-cli package upgrade

 Changes to be committed:
	modified:   aml-s9xx-box.tvb

PR #6659 broke upgrades for the aml-s9xx-box package.  That PR introduced
two new files in /boot which is a fat filesystem on this box.  The
standard package upgrade fails on a fat filesystem when files already
exist. PR #6659 failed to add the files to the remove list.  This
PR does that.
