Rename _waitpid() to safewaitpid() to avoid POSIX reserved identifier
namespace.

KNF nit: return value expressions should be surrounded by parentheses,
per style(9).

Ensure SIGCHLD is set to SIG_DFL, not SIG_IGN. POSIX allows (and
requires under XSI) that terminated child processes not leave zombies
if SIGCHLD is set to SIG_IGN, and it also allows execve() to leave
SIGCHLD set to SIG_IGN.
