userspace reboot: stop post-data services and wait for them to be killed

* Refactored code around stopping services a little bit to reuse it
  between full reboot and userspace reboot.
* Add a scope_guard to fallback to full reboot in case userspace reboot
  fails.
* In case of userspace reboot init will also wait for services to be
  terminated/killed and log the ones that didn't react to
  SIGTERM/SIGKILL in time.
* If some of the services didn't react to SIGKILL, fail userspace reboot.

Test: adb reboot userspace

init: use signalfd to catch SIGCHLD

Previously, if init received too many SIGCHLD signals, then the write to
signal_write_fd could fail with EAGAIN. The handler tried to log the
EAGAIN error, and init deadlocked if the interrupted init process had
already acquired a logging-related lock.

Test: manual

init: Allow clean system shutdown upon SIGTERM

This allows Android to cleanly shutdown when running in a PID namespace
in a way that does not rely on adbd running. This is useful to allow
Android to be running in a container and its lifetime managed by an
OCI-compliant tool.

Bug: 65415372
Test: `kill -TERM 1` as root is correctly dropped.
Test: `kill -TERM 1` from the init PID namespace causes init to cleanly shutdown.
