e7982b4ee9 cmd/sharefs: create directory as root
This optional behaviour is required on NixOS as it is otherwise impossible to set this up: systemd.mounts breaks startup order somehow even though my unit looks identical to generated ones, fileSystems does not support any kind of initialisation or ordering other than against other mount points.

ef1ebf12d9 cmd/sharefs: handle mount -t fuse.sharefs
This should have been handled in a custom option parsing function, but that much extra complexity is unnecessary for this edge case. Honestly I do not know why libfuse does not handle this itself.

2f8ca83376 cmd/sharefs: containerise filesystem daemon
This replaces the forking daemonise libfuse function which prevents Go callbacks from calling into the runtime. This also enforces least privilege on the daemon process.

This change should not change behaviour other than making output more consistent.

d597592e1f cmd/sharefs: rename fuse-helper to fuse-operations
This is not really just library wrapper functions, but instead implements the callbacks, so fuse-operations makes more sense.

da2bb546ba cmd/sharefs: remove readlink
This filesystem does not support symbolic links, so readlink is not useful, and unreachable in this case because of the check in getattr.

This is for passing files between applications, similar to android /sdcard.
