Disable xattrs in all mksquashfs calls

--chroot-squashfs-compression-options does not exist in live-build bookworm (1:20230502). The correct mechanism is the MKSQUASHFS_OPTIONS environment variable read by binary_rootfs. Export MKSQUASHFS_OPTIONS="-no-xattrs" before lb build so live-build's binary_rootfs picks it up, and add -no-xattrs explicitly to every direct mksquashfs call in build.sh (fast-path repack and the dormant split-layers function). Remove the invalid lb config option. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Mikhail Chusavitin	f3962422c8	Fix lb config option name for squashfs compression options --chroot-squashfs-options is not a valid lb_config option; the correct name is --chroot-squashfs-compression-options. Without this fix lb config aborts immediately, so the -no-xattrs flag (which prevents the "unable to read xattr id index table" boot failure) was never applied.

Mikhail Chusavitin	ee36e3c711	Strip xattrs from squashfs to fix boot failure Kernel squashfs driver fails with "unable to read xattr id index table" when the squashfs contains POSIX ACL xattrs (system.posix_acl_*) written by mksquashfs as unrecognised entries. This caused every built ISO to drop to an initramfs shell at boot. Add -no-xattrs to mksquashfs options so xattrs are stripped at build time. xattrs are not needed in a live read-only rootfs.

Mikhail Chusavitin	cca3b21d35	Revert squashfs layer split — live-boot cannot mount partial rootfs split_live_squashfs_layers moved /usr out of filesystem.squashfs into a separate 10-usr.squashfs, leaving a rootfs skeleton that live-boot (1:20230131+deb12u1) cannot mount: the initramfs panics with "Can not mount /dev/loop0 ... filesystem.squashfs". live-boot in bookworm expects a single self-contained filesystem.squashfs. Revert to the standard single-squashfs layout and remove the dead multi-squashfs guard in needs_full_build(). The split_live_squashfs_layers function is kept for future reference.
