Allow --v and --log-level switches simultaneous usage.

Allow --v and --log-level switches simultaneous usage.

The current implementation, in fact, doesn't support specifying both
"--v" and "--log-level" command line switches: only "--log-level" switch
will take an effect. This looks counterintuitive.

For example, browser_tests always start the browser with the
"--log-level" switch specified, so with current implementation there's
no way to enable vlogging in browser_tests using a command line.

The suggestion is, as both of the options refer to the same underlying
"min_log_level", to make the "--v" switch have a higher priority.

Do this in the same if statement as the command_line.HasSwitch() check above?
