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.

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.

056f5b12d4 cmd/sharefs: move translate_pathname body to macro wrapper
This is never called directly anywhere and it is simple enough to be included in the macro. This avoids passing the pointer around and dereferencing errno location, resulting in over 5% increase in throughput on the clang build. No change in the gcc build though.

54610aaddc internal/outcome: expose pipewire via pipewire-pulse
This no longer exposes the pipewire socket to the container, and instead mediates access via pipewire-pulse. This makes insecure parts of the protocol inaccessible as explained in the doc comment in hst.

Closes #29.
