perf hists browser: Add ui.show-headers config file option 



Adding ui.show-headers config file option to define if the histogram
entries headers will start visible or not.

Currently columns headers are displayed by default, following
lines in ~/.perfconfig file will disable that:

  [ui]
        show-headers = false
