makechrootpkg: move init_variables() to be part of main()

The reason it wasn't moved before was just to keep the diffs
(with --ignore-all-space) smaller, to make merging and rebasing work
easier.  Moving code around in a file tends to make that difficult.

But, readability wise, it belongs in main().
