init: dump stack when aborting
Dump init stacks when aborting either due to LOG(FATAL) or in
userdebug/eng builds due to signals, including signals from
sanitizers.
Doesn't work for static first stage init yet, b/133450393 tracks
that.
Also, ensure that LOG(FATAL) in child processes calls abort() in all
stages of init, not just 2nd stage init.
Bug: 131747478
Test: abort init in various ways and see stacks
Test: hang or crash in backtrace handler and see child reboot

# First stage init is weird: it may start without stdout/stderr, and no /proc.
