util: make spawndetached() handle subprocess early terminations
The file-based synchronization introduced by e22695b4472f hangs when the child
process fails before terminating the handshake, which the previous pipe-based
version handled correctly. To fix this, the parent polling loop was fixed to
detect premature terminations of the child process.
