[PATCH] log: fix WITH_SYSTEMD_JOURNAL guards

[Ben Chan]

Commit fd0bed1df ("log: Add support for journal logging") added a
configure option --with-systemd-journal to enable journal logging.
However, configure always defines WITH_SYSTEMD_JOURNAL, which is either
0 or 1. Thus, `#if WITH_SYSTEMD_JOURNAL` should be used instead of
`#if defined WITH_SYSTEMD_JOURNAL` to properly guard the journal logging
code.
