NIIBE Yutaka 6e422b5135 common: Fix gnupg_wait_processes.
* common/exechelp-posix.c (gnupg_wait_processes): Loop for r_exitcodes
even if we already see an error.

--

Cherry-picked master commit of:
	eeb3da6eb717ed6a1a1069a7611eb37503e8672d

The value stored by waitpid for exit code is encoded;  It requires
decoded by WEXITSTATUS macro, regardless of an error.

For example, when one of processes is already exited and another is
still running, it resulted wrong value of in r_exitcodes[n].
