There are cc_binary_prebuilt modules in the tree that are shell
scripts, and attempting to extract an elf ID from them results
in an error. Ignore too short files and files missing the elf
magic header the same way we do for elf files without an elf ID.

textproto, and also supports a merge mode to combine textprotos into
a output file for inclusion in the build artifacts.
