kp: bump to 0.12.6

Allow patches even when verification fails.
It may fix some device patch failed

To support certain devices that replace /system/etc/init/atrace.rc with /system/etc/init/hw/init.rc too early during post-data-fs, and to maintain compatibility with older devices below Android 12 that lack /system/etc/init/hw/init.rc, the openat RC redirection logic has been improved: it now matches multiple RC paths and applies the replacement on the first hit, while ensuring the restored RC strictly corresponds to the originally matched path to prevent cross-path corruption. Behavior on Android 12+ devices remains unchanged.
