scripts: recovery addon.d-v2 and env fixes

Browse Source 
- recovery addon.d-v2 requires /system and /system_root stay mounted
- find OUTFD from recovery update_engine for addon.d-v2 output
- fix finding OUTFD on addon.d failure with toybox ps
- simplify heredoc creation
- update to longer apex BOOTCLASSPATH
- save and restore any mountpoint symlinks encountered

Closes #2284
