perf ui/gtk: Setup browser window early

The ui__error/warning functions use gtk infobar or statusbar and pr_*
functions use statusbar too.  But after perf gtk context created but
those infobar and/or statusbar not yet set up, calling one of those
functions will get a segment fault.

Although current code has no problem, move these setting as early as
possible so that it can prevent the segfault from future change.
