Subject: [PATCH v2] perf tools: set browser mode right before setup_browser()

There are codes that print messages to the screen between assignment
of the use_browser variable and setup_browser().

But since the GUI browser is not initialized during that period,
all messages fail to show if the user passed the --gtk option
to perf as GTK is not initialized yet.

Reorder the code to assign use_browser variable right before
setup_browser() is called.
