webpack: Simplify copied files

Browse source 
As `files` is now the only entry in `info`, rename it to a `copy_files`
constant, and drop `info` completely.

Drop the "qualify" loop and add the src/ subdirectory to the path
directly. This is more explicit, thus easier to understand, and simpler.

Drop the now unused "vpath" function.
