Ignore SIGTRAP in child process on macOS

When running gn under Xcode (e.g. when debugging), the child process
is sent a SIGTRAP signal and immediately dies as it is not handled.
This makes gn consider that action, action_foreach and exec_script
have failed due to the signalled state of the child process.

To prevent this, ignore the SIGTRAP signal on macOS in the child
process.
