Florian Fischer 6f4d3b57f9 libc: fix waitpid not detecting process termination 
Since 452aa40770 and the change to
properly return processes exit codes in the status argument, the
status will never be EXIT_ZOMBIE(16) except a process was terminated by
signal(16).

Return from waitpid if either an error occurred (__res < 0) or
we got the status of a child process (__res == cpid).

Additionally fix the weird alignment of the closing braces.
