Four-bug fix from 4-agent verification wave on v0.5.30 outcome.
Bug 1 CRITICAL: --location=none made anaconda skip CollectKernelArgumentsTask
(installation.py:149-151). --append= args never collected, BLS entries
wrote with empty cmdline. Drop --location=none, let anaconda do its
bootloader path; broad transaction_progress patch already silences the
gen_grub_cfgstub class failure.
Bug 2 CRITICAL: kernel-install reads /etc/kernel/cmdline as source of
truth (per 90-loaderentry.install:84-95). Veilor never wrote that file
so kernel-install fell through to /proc/cmdline (live ISO's). Add
3-path write: /etc/kernel/cmdline (Path A canonical), /etc/default/grub
(Path B legacy), grubby --update-kernel=ALL (Path C last-writer guard).
Plus explicit kernel-install add per kernel after Path A write.
Bug 3: rescue BLS glob *-0-rescue-*.conf required trailing hyphen;
F43 uses *-0-rescue.conf. Fix: *-0-rescue*.conf (matches both).
Bug 4: set +e/set -e scope leak in %post. v0.5.30 closed manual
bootloader block with set -e which re-enabled errexit for the rest of
%post that was authored with set +e semantics. Result: any
non-guarded command failure aborted the LUKS args injection block.
Fix: remove the closing set -e.
