Add support for creating firmware patterns at build time 

Using the new generate_firmware_patterns script, generate a patterns
file in /firmware/dep11/<package>.patterns as we add a firmware
package onto media.

Deal with size changes as these are added/removed, and add them to the
md5sum.txt file on media too.
