base-files: Remove nand.sh dependency from emmc upgrade

emmc_do_upgrade() relies on identify() from the nand.sh upgrade helper.
This only works because FEATURES=emmc targets also tend to include
FEATURES=nand.

Rename identify_magic() to identify_magic_long() to match the common.sh
style and make it clear it pairs with other *_long() variants (and not,
say *_word()).
