src/meta-openembedded:plocate: upgrade 1.1.20 -> 1.1.22

Changelog:
==========
- Revert the updatedb change in 1.1.21 that did not open
  pruned paths; it broke pruning of paths that were not at the root
- Improve interactions between pruning and bind mount detection
  logic.
- Pruned paths are now not opened, which can be useful in certain
  cases. Note that this does not (yet) apply to filesystems that
  are pruned due to type and not due to paths; they are still opened
  and then immediately closed again.
