RFR 8184281: -Xlog:startuptime does not include call to initPhase2

[harold seigel]

Hi,

Please review this small JDK-10 fix for JDK-8184281.  The fix drops the 
need to specify "+module" in order to get Phase2 initialization timer 
information.  It will now be included when just -Xlog:startuptime is 
specified.

The fix was tested with the hotspot JTReg tests.

Thanks, Harold
