- Also remove generating .current control file as its obsolete in this design

- make `tmpfs_estimated_size` and `available_physical_memory_mib` readonly and global and only ever set once
- remove subshell from `get_rootfs_cache_list()`, new version `get_rootfs_cache_list_into_array_variable()` for sanity
- warns if `ROOT_FS_CREATE_ONLY=yes` is set during cached build path
- add a `wait_for_disk_sync()` after restoring rootfs cache
- fix logging sections for `build_rootfs_only()` and `prepare_rootfs_build_params_and_trap()` in `build_rootfs_and_image()`
- remove the logging section from `get_or_create_rootfs_cache_chroot_sdcard()` call in `build_rootfs_only()` (which is now itself logged)
- @TODO: `deploy_qemu_binary_to_chroot()` is leaking a qemu bin in rootfs cache!
