makechrootpkg: Avoid having code floating around outside of a function.
This means wrapping variable initialization in init_variables(), and the main program routine in main(). I did NOT put `shopt -s nullglob` in to a function. It make make sense to move init_variables() down into the main() function, instead of having it as a separate function up top (if this done, then the `-g` flag passed to `declare` in init_variables() can be dropped). However, in interest of keeping the `diff -w` small, and merges/rebases simpler, this isn't done here.
