Michael Pratt 54ac76c305 Remove unsafe ScopedSigaction 
ScopedSigaction is not async-signal-safe, so it cannot be used after fork.
Replace it with plain sigaction, which is safe. This is in a unique child
anyways, so it doesn't need any cleanup.

Jamie Liu bf65e06c5f Clean up some uses of fork() in tests. 
- Fix a few cases where async-signal-unsafe code is executed in a forked
  process pre-execve.

- Ensure that the return value of fork() is always checked.
