Logging: pass logging related cmd line options to utility process

Logging doesn't work in utility process due to the related command line
options are not passed to utility process. For example, run
" ./chrome --vmodule=unpacker=1 --enable-logging=stderr", DVLOG(1)
message in unpacker.cc can not be output correctly. This patch passes the
related command line options to utility process.

BUG=
TEST=--enable-logging=stderr --vmodule=unpacker=1, then open  chrome://extensions, drag a foo.crx in the page, you can see the DVLOG message " Installing extension ".
