Improve error handling and logging for LXC builds (#12208)
Prevent host-side error_handler from being triggered during in-container install/recovery by delaying re-enabling set -Eeuo pipefail and the ERR trap in misc/build.func until after install/recovery completes; add explanatory comments. Update misc/error_handler.func to fall back to BUILD_LOG if container-internal log path is unavailable, show the last 20 log lines when present, refine container vs host detection (check INSTALL_LOG file and /root), copy INSTALL_LOG into /root and write a .failed flag with the exit code for host-side detection, and ensure full-log output and container removal prompt are shown appropriately in host context. Tweak misc/core.func silent() output to include a "Full log" path and adjust formatting.
