sanoid: fix sudo for syncoid

[Tillerino]

Syncoid, which is one of the scripts in the sanoid package, calls sudo if the local user is not root.

The package adds /run/booted-system/sw/bin to the path of all scripts. If I understand correctly, this is to make sure to use the ZFS binaries of the OS rather than anything that the user might have installed - the binaries need to exactly match the file system daemon. The issue is that /run/booted-system/sw/bin also contains the raw sudo binary, which cannot be called:

> /run/booted-system/sw/bin/sudo echo
sudo: /run/booted-system/sw/bin/sudo must be owned by uid 0 and have the setuid bit set

This leads to the syncoid script failing when called as non-root.

To fix this, we add /run/wrappers/bin to the path before /run/booted-system/sw/bin such that the correct sudo is used.
