cygserver: Speed up non-debug scenario
_log/_vlog were always called so we always had a function call hit even
if we're not debugging. Expand on the debugging macros so the decision
to call _log/_vlog is done in the caller already. Also, make a log level
difference between syscall_printf and system_printf.
