Fix scripts

manager.sh + boot_patch.sh:
- all listed files from boot_patch.sh header are required for boot patching, but stub.apk was being removed so install_magisk via addon.d.sh would fail without it; leave it in place

addon.d.sh:
- remove old redundant recovery_actions call (it's also performed by setup_flashable in initialize)
- print ABI to match flash_script.sh output

boot_patch.sh:
- catch and abort on any errors from ramdisk.cpio patching in the future

util_functions.sh:
- fix hiding of mount_partitions /system_root umount stderr
- quote mount_apex .pb DEST name parsing charset for safety even though both work

Fixes #6828
