Change process spawning to inherit the parent's signal mask by default
Previously, the signal mask is always reset when a child process is started. This breaks tools like `nohup` which expect `SIGHUP` to be blocked. With this change, the default behavior changes to inherit the signal mask. This also changes the signal disposition for `SIGPIPE` to only be changed if the `#[unix_sigpipe]` attribute isn't set.
