syslogd: convert dummy functions to statics and get rid of IF_FEATURE_* checks

Browse Source 
As suggested by Mike. No bloat-o-meter difference, but a bit nicer to look at.
We cannot convert the call to log_to_shmem() as it checks for G.shbuf outside
the function, and G.shbuf is only available when IPC support is enabled.
