--add-file: copy any host file into the image (#181)

pack --add-file SRC:DST copies a host file into the image at DST. A bare absolute
--add-file SRC keeps the host path. Until now --ca-certs and --tz each added one fixed
file, and there was no way to add another. A program that reads a configuration file or a data
file at runtime now packs without a wrapper step. The flag repeats and takes regular files
only. The add-file key in scratchsmith.toml takes the same list. A missing source, a
directory, or a DST that is already in the image fails the pack and names the path. The
layer writer canonicalizes modes, so in an image the file lands owned by uid 0. Its mode is
0644. When the source is executable, the mode is 0755.
