Add a version of package_extract_file that returns the file data as its return value (to be consumed by some other edify function that expects to receive a bunch of binary data as an argument). Lets us avoid having two copies of a big file in memory (extracting it into /tmp, which is a ramdisk, and then having something load it into memory) when doing things like radio updates.
