eb22a8bcc1 cmd/hakurei: move to cmd
Having it at the project root never made sense since the "ego" name was deprecated. This change finally addresses it.

31aef905fa sandbox: expose seccomp interface
There's no point in artificially limiting and abstracting away these options. The higher level hakurei package is responsible for providing a secure baseline and sane defaults. The sandbox package should present everything to the caller.

1a8840bebc sandbox/seccomp: resolve rules natively
This enables loading syscall filter policies from external cross-platform config files.

This also removes a significant amount of C code.

31b7ddd122 fst: improve config
The config struct more or less "grew" to what it is today. This change moves things around to make more sense and fixes nonsensical comments describing obsolete behaviour.

e9a7cd526f app: improve shim process management
This ensures a signal gets delivered to the process instead of relying on parent death behaviour.

SIGCONT was chosen as it is the only signal an unprivileged process is allowed to send to processes with different credentials.

A custom signal handler is installed because the Go runtime does not expose signal information other than which signal was received, and shim must check pid to ensure reasonable behaviour.
