Bug 1346132 (part 1) - Initialize Mozilla logging earlier in nsAppRunner.cpp. r=erahm.

Browse Source 
The following functions all call NS_LogInit() (either directly or via
ScopedLogging) and then call LogModule::Init() very shortly after:
XRE_InitChildProcess(), NS_InitXPCOM2(), NS_InitMinimalXPCOM(),
XRE_XPCShellMain().

XREMain::XRE_main() does not, however. This prevents us from using MOZ_LOG
easily in the profiler, because the profiler starts up earlier than logging in
the browser.

This patch adds an early LogModule::Init() to XRE_main(), just after the
NS_LogInit().
