xserver: add RemoveLogFile()

Simple unlink() call to the logfile in use. The log file is only removed if
the server was started and terminated or finished successfully. If it was
never started or the startup failed for some reason, this function does
nothing. Behaviour can be overridden by forcing the removal.
