base-files: upgrade: nand: allow custom fw extraction in nand_do_upgrade()

Browse Source 
By default nand_do_upgrade() can only deal with raw and gzipped firmware
files. Vendors often use custom firmware containers. Allow passing
custom extraction command to allow using nand_do_upgrade() with vendor
firmwares.
