Arnaldo Carvalho de Melo c4fe52a8ee perf tui: Fix last use_browser problem related to .perfconfig
When we moved to using ~/.perfconfig to set the value of use_browser,
it changed from a boolean to an int so that the convention used for
use_pager was followed.

That convention is:

-1: unspecified, that is what use_{browser,pager} is initialized
 0: Don't use the browser (should be TUI), because was explicitely
    set to 0/off/false on ~/.perfconfig [tui] cmd =, or because
    we're redirecting the stdout to a file or piping it to some
    other command (!isatty()).
 1: Use the TUI

Some code was not properly audited and continued testing it as a
boolean, this seems to be the last one.
