feat(tvix/store): fix ctrl-c handling on mount command

Browse source 
This enables the tokio `signal` feature, and registers a ctrl_c signal
handler, which will use the unmount handle to unmount in case a ctrl-c
signal is received.

This avoids having disconnected mountpoints when Ctrl-C'ing a
`tvix-store mount` invocation.

In case the filesystem is unmounted externally (via `umount /path/to/
mountpoint`), the future is waiting for the signal is never resolved and
the task is stopped.
