perf hists browser: Override ui_browser refresh_dimensions method

Browse Source 
This requires some more work so that we can really just use the width of
current entries when we want to partition the screen.

Right now its just a prep patch so that we can have where to update
ui_browser->rows when introducing the column headers line, that will be
togglable, so we need to update it everytime we refresh the dimensions
of the browser.
