flock: fix hang when parent ignores SIGCHLD
If flock is executed from a process which has set SIGCHLD to SIG_IGN, then
flock will eat cpu and hang indefinitely if given a command to execute.
So before we fork(), make sure to set SIGCHLD handling back to the default
so that the later waitpid() doesn't freak out on us.
[kzak@redhat.com: - add a check for waitpid() return value]
