Something like this should work (untested):

  (package
    (origin
      [...]
      (snippet
        #~(begin
            [...]
            (delete-file "third_party/md5/md5.cpp") ; maybe not necessary?
            (copy-file #+(search-auxiliary-file "jsonnet-md5.cpp")
                      "third_party/md5/md5.cpp")
            [...])))
    [...])

"git diff" has an option "--irreversible-deletes" and "--break-rewrites"
which should reduce the size of the patch, by not including the previous
version.
