e42ea32dbe nix: configure sharefs via fileSystems
Turns out this did not work because in the vm test harness, virtualisation.fileSystems completely and silently overrides fileSystems, causing its contents to not even be evaluated anymore. This is not documented as far as I can tell, and is not obvious by any stretch of the imagination. The current hack is cargo culted from nix-community/impermanence and hopefully lasts until this project fully replaces nix.

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.

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.

2e5362e536 cmd/sharefs: opaque setup state
This allows unrestricted use of the type system and prepares setup code for cross-process initialisation.

6d3bd27220 cmd/sharefs: expand fuse_main
This change should not change behaviour other than making output more consistent.

7bfbd59810 cmd/sharefs: implement shared filesystem
This is for passing files between applications, similar to android /sdcard.
