ksud/installer: /odm handling (#2513)

Browse Source 
we move the folder out of system if it exists in real filesystem and it
is not a symlink.
this is already supported on init_event.rs so only handle_partition
logic was needed to make it happen

since KernelSU is using overlayfs, we need to move these out.
