mac content shell drt: Don't DLOG(FATAL) during font loading in debug builds

mac content shell drt: Don't DLOG(FATAL) during font loading in debug builds

The problem was that `[[NSBundle mainBundle] bundlePath]` returned 
Content Shell.app's bundle in debug builds, but
Content Shell.app/Contents/Versions/Content Shell Helper.app's bundle in debug
builds.

This is already handled in content/shell/paths_mac.mm, so use the code in there
(and move the initialization for that code to happen before
WebKitTestPlatformInitialize is called).

BUG=179805
TEST=`echo compositing/absolute-position-changed-in-composited-layer.html | out/Debug/Content\ Shell.app/Contents/MacOS/Content\ Shell --dump-render-tree` passes.

does this also fix the http/tests/inspector tests timing out?

File content/shell/shell_main_delegate.cc (right):
