log: Fix compilation error on non-systemd systems

Browse source 
Commit 262bdae0330e used symbols which are only available if systemd
support was compiled in. Fix by using the appropriate #ifdef guards.

Also document the resulting PULSE_LOG_JOURNAL environment variable
behavior if systemd journal support was not compiled in.

[Diwic: changed wording slightly.]
