Archit Gupta 2efcf8291e lkl: Let mount find lklfuse mount helper
This enables mount to find lklfuse when mounting with the type
"fuse.lklfuse". With this fix, lklfuse can be used to mount filesystems
with NixOS filesystem options.

This is the same fix as has been applied to bindfs, mergerfs, and
apfs-fuse.
