Handle returned events

When IO_ERR, IO_HUP or IO_NVAL is delivered, Launchpad tries to recover
the socket. If it's failed, Launchpad uses abort() to terminate itself
abnormally.

Fix SMACK error

When calling sd_journal_stream_fd() is failed, the child process used
the fds of the parent. It causes SMACK errors.
To prevent SMACK errors, the child process uses "/dev/null" for standard I/O
redirection if calling sd_journal_stream_fd() is failed.
