Elliott Hughes 71ba5899ae Rewrite system(3) to use posix_spawn(3).
We saw crashes from pthread_exit+debuggerd on LP32
(https://issuetracker.google.com/72291624), and it seems like the
equivalent problem should exist with system(3). I fixed posix_spawn(3)
as part of that bug, so the easiest fix is probably to reuse that.

Bug: http://b/72470344
Test: ran tests
