Apply security updates after debootstrap is complete, as debootstrap can only use one repository when creating chroot.

Does this accomplish anything? Ren'Py should be compiling everything it doesn't dynamically link against itself. So I'm not clear what this will improve.

Mainly applying security updates for glibc and other important packages.

For example, apt will upgrade these packages:
