In order to support package managers such as Cargo (Rust) or Go, we
want to run some custom logic after the main download, but before
packing the tarball and checking the hash.

To implement this, this commit introduces a concept of download
post-processing: if -p <something> is passed to the dl-wrapper, then
support/download/<something>-post-process will be called.
