Remove extra compiled-on stamp.

Don't use __TIMESTAMP__; that gives the last compile time of
RageLog.cpp, not the last build time.
Put the current time in info, instead of trace, so we can compare
times when we receive more than one log, to make sure they really
match up (we occasionally get crashinfo.txt from a previous crash,
in which case only info.txt and log.txt are relevant).
