build: Remove installworld backup check

Dillon wants to rework backup functionality.
1. Remove any check that can halt installworld
2. Backup world automatically and store it in /usr/obj/world_binaries
3. Keep manual backup commands, they still it WORLD_BACKUP as before
4. Get rid of days check

This commit accomplished step 1.
