util/me_cleaner: Pull the latest changes from upstream

Browse Source 
Relevant changes (commit 250b2ec):
 * Fix a bug for ME6 Ignition images.
 * Fix signature checking for ME11 and later.
 * Add command line arguments.
 * Add an option to relocate the FTPR partition to the top of the
    ME region, recovering most of the ME region space.
 * Print the image minimum size.
 * Add write boundary checks, to prevent writes on other regions
    in case of bugs.

The new changes have been tested on multiple platforms by the
me_cleaner users. They have been tested also on the author's
X220T with coreboot, where the ME region has been shrinked up to
84 kB without any issue.
