39e49549e6 The current implementation of Sandbox::Terminate results in timeout's being reported to coroner in cases where a Restart or Terminate with graceful exit is requested.
This change requests an exit from the sandboxee and then awaits the result either with a timeout of 1 second (the grace period) or else with infinite duration - which would then report the timeout again.

1bad376e42 Block sigaltstack with ENOSYS by default
`absl::GetStackTrace` on Aarch64 since
bb7bbb12c7 will call sigaltstack.
`absl::Mutex` in debug mode uses `absl::GetStackTrace` causing many new syscall violations. An error in the sigaltstack should be tolerated, so this will fix the issue without opening up the policy too much.

3ea315858d Remove mutexes from Comms
It was never fully thread-safe.
e.g. calling SendProtoBuf concurrently from 2 threads
could result in a data race.
Also not all users need the thread-safety thus it's better left off to be done externally by the ones that require it.

e23acfd7e7 Made slight optimizations in Sandbox2's comms.
The optimizations are:
* Reduced the number of calls to `write` (originating from `SendTLV()`) from 3 to 1-2 (depending on size of the payload).
* Reduced the number of calls to `read()` (originating from `RecvTLV()`) from 3 to 2.
