archinstall 4.3 writes limine.conf to <target>/<esp_mount>/EFI/arch-limine/
limine.conf for UEFI non-removable installs (lib/installer.py:1487), not
to /mnt/boot/limine.conf as our code assumed. Older archinstall versions
used different paths.
Probe the 4.3 paths (arch-limine, BOOT, limine subdir) and the legacy
/boot/limine.conf in order; pick whichever exists. Error message now
lists everywhere it looked so future drift is easy to diagnose.
